If you have just updated your Mozilla Firefox browser as of late and you noticed that it’s showing wrong or no bookmark favicon at all, then read on as this post will provide you with potential solutions that can help you resolve the problem. The basic thing you can do to fix it is to either refresh or reset the cache for favicon and then force restart the favicon service. However, if you’ve already tried this and it didn’t work, then there are still other options you can try. You can try to rebuild the configuration file for the favicon or restart the favicon service. You could also try disabling all the add-ons on your browser or scan your computer for adware. For more details, refer to each one of the options laid out below.
Option 1 – Try to rebuild the favicon configuration file
Mozilla Firefox actually creates a file each time you bookmark a webpage and this is called “favicons.SQLite”. This file is located on your computer and for you to fix the issue in Firefox, you need to rebuild this file and in order to do that, follow these steps:
First, you need to unhide the hidden files in your computer by enabling the “Show hidden files” option so that you’ll be able to see the hidden files in your computer.
After that, navigate to this path: C:Usersyour_usernameAppDataLocalMozillaFirefoxProfilesyour_profile_name
From there, you need to find the “favicons.SQLite” file and once you found it, delete it.
Next, you have to open the Firefox browser and create the same favicon configuration file which should be automatically created.
Now check if you can now see bookmark favicons on your Firefox browser or not.
Option 2 – Try to restart the favicon service
If the first option didn’t work, you can try to restart the favicon service instead. Restarting the favicon service can help if you do not see the correct bookmark favicon on your Firefox browser. To restart this service, follow the steps below.
You need to first open the Firefox browser and in the address bar, type “about:config” and tap Enter.
After that, you will see a page that displays a warning message. On that page, you need to click the “I accept the risk!” button to proceed.
Next, using the search box on the page, look for the “devtools.chrome.enabled” option. The value for this option should be set to “False” by default.
Double click on this option to set its value to “True”.
Once done, go to Menu > Web Developer > Browser Console or you could also tap the Ctrl + Shift + J keys, alternatively.
Afterwards, paste this command in the pop-up window that appears and then tap the Enter button: var fS = Components.classes["@mozilla.org/browser/favicon-service;1"] .getService(Components.interfaces.nsIFaviconService); fS.expireAllFavicons();
Once you’re done, restart your Firefox browser to check if it fixes the problem or not.
Option 3 – Try to disable all the add-ons in Firefox
The next option you can try to fix the problem is to disable all the installed add-ons in Firefox. More often than not, add-ons can cause issues in the browser so it is possible that one of the add-ons in Firefox is causing it to show incorrect or no bookmark favicon. To resolve this problem, you have to disable all the add-ons by opening Firefox and then going to Menu > Add-ons or you could also tap the Ctrl + Shift + A keys. After that, go to the Extensions section and click on the respective Disable buttons for each one of the add-ons. Once done, restart your computer and check if you can now see the bookmark favicons or not.
Option 4 – Try scanning your computer using Windows Defender
It is possible that the bookmark favicon problem is caused by some adware in the Firefox browser so you have to scan your computer to check by using security programs like Windows Defender.
Tap the Win + I keys to open Update & Security.
Then click on the Windows Security option and open Windows Defender Security Center.
Next, click on Virus & threat protection > Run a new advanced scan.
Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.
If your VPN software blocks and disconnects the Internet or Wi-Fi connection as soon as it is connected, read on as this post will give you fixes to resolve the problem. This kind of issue is odd but not unheard of. Many users use VPN for privacy and security but if it causes internet connection problems, you have to pin down the root cause of the problem and fix it in order to continue browsing the internet with privacy and security.
Here are some suggestions you need to check out to resolve the issue between your VPN software and network.
Option 1 – Try installing the latest version of the TAP adapter
Since all VPN software uses a TAP adapter which is mostly from OpenVPN, you might want to download and install the TAP adapter driver to resolve the problem.
Option 2 – Run the Network Adapter Troubleshooter
Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
Next, scroll down and select the “Network Adapter” option from the right pane.
Then click on the Run Troubleshooter” button.
After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.
Option 3 – Configure the client computer to use the default gateway
This kind of connection problem can occur when you configure the VPN connection as the default gateway on the remote network. In such a case, the VPN settings override the default gateway settings (TCP/IP settings). Thus, you have to configure the client computers in order to use the default gateway setting on your local network for internet traffic as well as a static route on the remote network for VPN-based traffic.
Option 4 – Try to use the Google Public DNS
You might want to change your DNS to Google Public DNS as it could help you resolve the internet connection problem caused by your VPN. To do so, follow the steps below.
The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
Next, click on the “Change Adapter Settings” option.
After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
Right-click on your network connection and click on Properties.
Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.
Option 5 – Try checking the settings of your VPN software
If your VPN software has a built-in “kill switch” it prevents any internet usage every time there is a problem in connecting with the VPN server which explains why your internet connection is disconnected when your VPN software is connected.
In addition, you could also try to change your VPN software’s protocol since all VPNs support multiple protocols. It could be that the protocol your VPN uses is blocked so try changing to another protocol and see if it fixes the problem.
Option 6 – Update the Network Adapter drivers
You might also want to update the Network Adapter drivers by following these steps:
Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
Then right-click on each one of the Network drivers and update them all.
Restart your PC and see if it helped in fixing the BSOD error.
Note: If updating the network drivers didn’t help in fixing the “Windows could not find a driver for your network adapter” error, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.
To reinstall the network adapter driver, refer to these steps:
Open the Devices Manager from the Win X Menu.
Then locate the device drivers and right-click on them to open the Properties.
After that, switch to the Driver tab and click on the Uninstall Device button.
Follow the screen option to completely uninstall it.
Finally, restart your computer. It will just reinstall the device drivers automatically.
It really sucks when you can’t fully enjoy the newest version of your favorite OS.
Windows 11 is still relatively fresh and consequently has some annoying little bugs that really ruin our experience. The good news is that you’re not alone and most of them are easy to fix.
Here are 5 commonly reported Windows 11 issues and what you can do to get rid of them.
1. Windows 11 audio problems
One of the absolute most irritating things in the world is struggling with the sound on your computer. Windows 11 users have reported facing the issue of low or no sound. If you’re currently experiencing the same frustration, you can be relieved. Chances are fixing it will only take a few minutes.
The first thing to check would be whether you accidentally muted your device by pressing the mute button on your keyboard. Yes, we know it sounds a lot like the old “have you tried turning it off and on again?” But it’s important to leave no stone unturned, and the most obvious things are usually the ones we easily overlook.
Moreover, if you have several audio output sources, check whether the right one is selected. You can do this via the Action Center or through Settings. If you want to use the same source every time, we also recommend you set it as the default one.
It’s also important to have a good, up-to-date audio driver. More often than not, this will be the true cause of your audio struggles. Make sure to update your driver, and if that doesn’t work out, you can always un- and reinstall it or install a different one.
Lastly, if all attempts remain unsuccessful, run the audio troubleshooter to figure out what’s actually going wrong.
2. Unable to find files
Such a powerful new operating system, yet it can’t seem to do the simplest thing imaginable? The File Explorer not responding on Windows 11 is one of the most frustrating and most common problems with Microsoft’s newest iteration of its awesome OS.
However, 9/10 times it can be fixed by simply restarting your PC. You could also try killing the Windows Explorer process in the Task Manager and then rerunning it.
If these don’t help, check whether there are any pending Windows 11 updates. A single missing update can compromise your PC’s functionality, so always make sure to install them all on time.
Should none of that work, then there are other ways to solve the File Explorer problem. However, then the issue is probably a bit deeper and it’s no longer in the ‘easy fix’ territory.
3. Start menu not working
Just like the File Explorer, the Start menu is a fundamental element of your OS. So, it’s only natural that its malfunction grinds your gears. It may be more customizable than on previous Windows versions, but it doesn’t always work smoothly.
If you’re facing the so-called Start menu critical error, there are a few things this could be caused by. Usually it means you turned off your system while an important update was still being installed, there is a corrupt file on your PC, or Windows forcefully stopped a program.
Whatever the reason, the solution should be pretty simple. Try the basic steps: restarting your File Explorer (like we explained above) and signing out and back into your account. If that doesn’t do anything, you may want to try uninstalling third-party start menu apps (if you have any), since they can interfere with your default programs’ functionality.
Now, those are the easy fixes. If you get nowhere with them, you might need to identify the root cause and search for more complex solutions than that.
4. Snipping tool not working
Our beloved screenshot tool was introduced with Windows 10 and Microsoft decided to keep it. However, you were probably just as disappointed as us when you tried to run it and failed.
Normally, this can be fixed by installing the latest Out-of-band (OOB) update, or even pending updates in general. Even if your system appears to be up-to-date, run the checker just in case.
Another cool thing Windows 11 lets you do is ‘Repair’ and ‘Reset’, which is the easiest way to troubleshoot your Snipping tool. If this fails, you can also try the good old un- and reinstall method. Simply uninstall the tool through the Control Panel and reinstall it from the Microsoft Store.
Furthermore, in the case of an upgrade from Windows 10 to 11, it may be that the old Snipping tool version is interfering with the launch of the new one. If you don’t care that much about the additional options available with the enhanced screenshot tool, you can use the old version instead.
Simply go to your C Drive, find the Windows.old folder, search for the tool and open it from there. Make sure to pin it to your taskbar as well, if you know you’re going to use it often.
5. Can’t install the latest update
The latest Windows 11 version, 22H2, has brought tons of enhancements to our dearest operating system. Unfortunately, a lot of users still haven’t had the opportunity to experience it. A mere update of your OS version should be the one thing that goes smoothly, but sometimes that’s not the case.
Failure to install 22H2 can be caused by a few things. Most commonly, the issue is caused by lack of storage space or corrupted files, but there could be other culprits.
There are a couple of things you could try. For example, it’s crucial that your drivers be up-to-date and some important services be enabled. These are: Windows Modules Installer, Background Intelligent Transfer Service, Cryptographic Service, Windows Update services.
To enable them, search ‘Services’, find the service you need and right-click on it. Open ‘Properties’ and select the startup type ‘Automatic’.
It may also be necessary to unplug all peripherals that aren’t crucial and disable third-party antivirus tools until after the update is finished.
Ultimately, you can run the Windows Update troubleshooter to detect and fix other possible issues.
Summary
Tiny bugs like these are nothing out of the ordinary. That said, we still all hate when they happen.
Hopefully some of our solutions have helped you to a smoother Windows 11 experience. But if you’re still struggling, feel free to reach out to us. We’d be happy to help!
Experiencing issues while using Remote Desktop connections is not uncommon. One of the issues that users encountered recently while trying to connect to their Remote Desktop network is the error saying, “Your credentials did not work, The login attempt failed”. If you are one of these users, then you’ve come to the right place as this post will walk you through fixing the problem.
When facing this kind of problem, the first thing you can try before you do some troubleshooting steps is to verify the credentials. But if you are certain that you’ve entered the correct credentials just like what other users reported, then it’s completely a different matter. Based on the reports, this error is common on newly installed versions of Windows 10 or after reinstalling the operating system which could mean that the problem might be due to the Windows security policies or the username might have been recently modified. The latter case is a possibility especially if you’ve reinstalled Windows 10 and had entered a new username. In such a case, you will really have a difficult time connecting to your Remote Desktop connection since its credentials do not really automatically change.
If you’ve verified that your credentials are correct, then now’s the time you troubleshoot the problem with the help of the potential fixes provided below. Just make sure that you follow each one of them in sequence.
Option 1 –Try to run the Network Adapter troubleshooter
To run the Network Troubleshooter, refer to these steps:
Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
Next, scroll down and select the “Network Adapter” option from the right pane.
Then click on the Run Troubleshooter” button.
After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.
Restart your computer.
Option 2 – Try to change the network profile from public to private
According to some reports, this error occurs on systems where the network profile was set to public. Thus, you need to change the network profile to private to resolve the problem. How? Refer to these steps:
Go to Start and from there click on Settings > Network & Internet > Status.
Next, click on the “Change connection properties” option.
After that, set the radio button of Network Profile from Public to Private.
Wait for a couple of seconds until the system is done applying the changes you’ve made and then see if you can now connect to the Remote Desktop connection.
Option 3 – Try changing the account username
As mentioned, one of the possible causes for this error is the reinstallation of the operating system. You might have changed the username for the system but it does not really change the username of the Remote Desktop connection as well. Thus, you have to change the username back to what it was before you’ve reinstalled Windows 10.
Option 4 – Try modifying the Windows Security Policy
You can also try to edit the Windows Security Policy as it could help in resolving the error. This Windows Security Policy, when enabled, will not allow non-admin users to log on to the Remote Desktop connection. So if you want to allow non-admin users to use the Remote Desktop connection, then you need to modify this policy. Note that you can only do that if you are the admin of the system yourself.
Tap the Win + R keys to open the Run utility.
Then type “secpol.msc” in the field and tap Enter or click OK to open the Local Security Policy.
After opening the Local Security Policy window, select Local Policies > User Rights Agreement located on the left pane.
Next, double click on “Allow log on through Remote Desktop Services” located in the right pane.
And in the next window that appears, select Add user or group.
After that, type in the username of the intended non-admin user under the “Enter the object names to select” column.
Once done, click on the Check Names button to fix the username and then click OK to save the changes made.
Restart your computer.
Option 5 – Use the Group Policy Editor
Tap the Win + R keys to open the Run dialog box and then type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
Next, navigate to this path: Computer Configuration > Administrative Templates > System > Credentials Delegation.
Double click on the “Allow delegating default credentials with NTLM-only server authentication” policy setting located on the right pane to edit it.
After that, shift its radio button to Enabled and click on Show.
Then type “TERMSRV/*” in the Value box and click OK.
Now repeat the same for the following policy settings:
“Allow delegating default credentials”
“Allow delegating saved credentials”
“Allow delegating saved credentials with NTLM-only server authentication”
Once you’re done, restart your computer and see if the problem is fixed.
Microsoft has released Windows 11 as a public beta release for all the people that are not willing to be in the insider program.
Beta release as of this moment is identical to Insider Preview build 22000.100. and updates will not roll so fast as in insider preview and it is marked as unstable release, same as insider build.
I would not install Windows 11 beta on the main PC since some drivers still have issues and may lead to some blue screens.
Be aware that the beta build will have all Windows 11 system requirements including TPM 2.0. This is a big difference from insider build which can be installed on systems lacking official requirements.
So basically if you have a spare PC that could run Windows 11 install it so you can see what it brings and feel it so you can make a decision will upgrade once it is released later this year.
The use of Biometrics is supported by Windows 10. Aside from that, it also supports PIN, password, picture password on all computers and if your computer has the proper hardware, Windows 10 also supports facial scanning, iris scanning, and even fingerprint scanning. You can see all these exciting features inside Settings > Accounts > Sign In Options.
On the other hand, you can’t really expect to make use of all the above-mentioned features since it depends if the hardware is available to support them. One of the most interesting features is the use of Biometrics which is really useful in workplaces and so this post will show you how you can enable or disable the Domain Users Sign In on Windows 10 using Biometrics via Registry Editor or Group Policy Editor.

Now exit the Group Policy Editor and restart your computer to apply the changes made properly.
Installing or updating Google Chrome does not always go smoothly as there are times when it also encounters some errors like the error code 0x80072EE7. This kind of error in Chrome is most likely caused by the Windows Firewall or third-party Firewall (if you’re using one) that blocks the installation or update process. Aside from this known culprit, there are also other factors to consider such as corrupted or incompatible installation files or it could also be caused by some issue with your internet connection.
If you face this kind of problem when installing or updating Chrome, you will see the following error message on your screen:
“An error occurred while checking for updates: Unable to connect to the Internet. If you use a firewall, please whitelist GoogleUpdate.exe. (error code 7: 0x80072EE7 — system level).”
Whatever the cause of this error is, you need to use the options prepared below to fix it.
Option 1 – Whitelist the “googleupdate.exe” in Firewall
If the issue is really caused by the Firewall, you need to whitelist the googleupdate.exe program to fix the error. To do that, follow these steps:
Tap the Win + E keys to open the File Explorer.
Next, copy and paste the following location in the address bar and tap Enter to go there.
Control Panel/All Control Panel Items/Windows Defender Firewall/Allowed apps
After that, click on the Change Settings button, and from the given list, look for Google Chrome.
Now check both Private and Public connections for it and then click on OK and see if it fixes the error or not.
Option 2 – Disable the proxy server for LAN
If the problem has something to do with your internet connection, then you can try disabling the proxy server for LAN and see if that helps.
Tap the Win + R keys to open the Run dialog box.
Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
After that, go to the Connections tab and select the LAN settings.
From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
Now click the OK and the Apply buttons.
Restart your PC.
Note: If you are using a third-party proxy service, you have to disable it.
Option 3 – Check your VPN
If you are using a VPN application, then this option should apply to you, if not, skip this option and proceed to the next one. There are times when VPN software causes some issues like this error. If that’s the case, you can try to disable your VPN temporarily and see if the error is resolved or not and if turns out that your VPN is the culprit, you have to uninstall it and install a new one or its latest version. To uninstall it, follow the steps below.
Tap the Win + R keys to open the Run dialog box
Then type “appwiz.cpl” in the field and hit Enter to open the Programs and Features in Control Panel.
From there, look for the VPN service you are using, select it and then click on Uninstall to remove it.
After that, restart your computer and try to install the latest version of the program again. It should work now. If not, proceed to the next available option below.
Option 4 – Try to run the Chrome Cleanup tool
You might want to run Google Chrome’s built-in Malware Scanner & Cleanup tool as it could also help in getting rid of any unwanted ads, pop-ups, and even malware, as well as unusual startup pages, toolbars, and anything else that might overtake the network and could affect the performance of the browser.
Option 5 – Reset Google Chrome
Before you proceed, make sure that the Chrome browser is not running anywhere in the background via Task Manager. Once you’ve made sure that it’s no longer running, refer to these steps:
Tap the Win + R keys to open the Run dialog box.
Then type “%USERPROFILE%AppDataLocalGoogleChromeUser Data” in the field and tap Enter to open this location.
From there, look for the Default folder and then tap the Shift + Delete button and if a confirmation prompt appears, click on Yes.
After deleting the Default folder, open Google Chrome and click on the three vertical dots icon located in the top-right corner to open the menu.
Next, click on Settings and scroll down and then click on Advanced to open the Advanced Settings.
Then scroll down until you see the “Reset and clean up” section and click the “Restore Settings to their original defaults” option.
After that, you will see a confirmation box and from there, click on the Reset settings button to reset your Google Chrome browser.
Hello and welcome to our Business Email Etiquette. Most people have experience in writing emails at some point before in their lives. However, the emails an average person writes are probably personal emails and not mails for work purposes.
Emails you send to friends are incredibly different in content and context to business emails you would send to customers or employers or even other colleagues in your workforce.
So, if you have a job that involves you writing emails to people in business style, learning business email etiquette is an absolute must for you.
1. Heading layouts
When you are sending emails to friends, you generally lay them out like a memo. This means there is very little detail in the layout besides basic greetings and paragraphs, usually starting with the greetings.
However, with a business email, it is best to lay it out exactly like you would lay out a formal letter. You need to put the company’s address in the right-hand corner and the date as well. Only then must you go on to the greetings.
This will make your email look more formal, making you seem like a professional who knows what they are doing as opposed to someone who just couldn’t be bothered spending the extra time to get the layout right.
2. Proper greetings
When you are sending an email to a friend, you usually greet them informally. If their name was Mary Johnson, you’d probably start your letter with a ‘Hey Mary’ or a ‘Hello Mary.’
However, this is not considered a professional way to write an email to a customer or other important person in your business. Again, you must use the proper method that you would greet someone with were you writing them a formal letter instead.
If your customer is Mary Johnson again, you should greet her with respect. ‘Dear Ms. Johnson’ would be the most appropriate way to start off your letter’s actual body in this case. If you do not know the recipient’s name, then you should start with a simple ‘Dear Sir or Madam.’
Politeness will always get you incredibly far, no matter what line of work you are in.
3. Informal language
You should get straight to the point with your email. Don’t dawdle on with it like you would if chatting to a friend and don’t write it how you would speak either.
You use language that sounds impressive and smart while not using such obscure language that your recipient doesn’t know what you are saying. All the time, you must keep it informal where possible, possibly even impersonal as well.
It will make you seem very professional in the long run.
4. Signing off
When you are sending your email, you must end it as you would with a letter also. Don’t just say ‘Bye’ and your first name; that is too personal.
You need to say ‘yours sincerely if you know the name of the recipient and ‘yours faithfully’ if you do not. Then you should end with your full name and whatever position you have at the company. (CEO, technical staff etc.)
So there you have it! All you need to do now is to show your boss that you can handle the emails from now on!

You'll be brought to a Device Summary page which tells you your Kindle email as well as the type of device it is.
You now need to approve your personal email, so that when the Kindle receives your PDF, it knows to download this. Make sure the email you approve is the one you're planning to send documents to your Kindle from otherwise it won't work. To approve your email address follow the steps for finding your Kindle email address but instead of selecting 'Devices' in the top bar, click 'Preferences'.
Scroll down this list until you find Personal Document Settings, and select this option so it expands into more options. From here, scroll down until you find 'Approved Personal Document E-mail List'. This list will show people who can email stuff to your Kindle, Below the emails is an option to 'Add a new approved e-mail address', which you should select. Enter your email address and click 'Add address' to get yourself approved.
Head over to your email client of choice, attach the file to an email, and send the email to your Kindle email address. You're able to send multiple documents at once, so if you have loads of files you want on your Kindle, you don't need to send separate emails. If you're sending over a PDF file, you can ask Amazon to automatically convert the file into a Kindle one, which lets you annotate the sections and change the font size. Simply put the word 'convert' as the subject line and the rest will be handled for you. 'Sync Your Kindle'.
Microsoft has released Windows 11 as a public beta release for all the people that are not willing to be in the insider program.
Beta release as of this moment is identical to Insider Preview build 22000.100. and updates will not roll so fast as in insider preview and it is marked as unstable release, same as insider build.
I would not install Windows 11 beta on the main PC since some drivers still have issues and may lead to some blue screens.
Be aware that the beta build will have all Windows 11 system requirements including TPM 2.0. This is a big difference from insider build which can be installed on systems lacking official requirements.
So basically if you have a spare PC that could run Windows 11 install it so you can see what it brings and feel it so you can make a decision will upgrade once it is released later this year.
