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.

Device drivers are needed in order for the hardware and software to communicate in an operating system. Some of these drivers are digitally signed. These kinds of drivers are drivers that are signed by their issuing authority in a way that the end-user or any third party won’t be able to modify them. And there are times when you encounter an error that says, “Windows requires a digitally signed driver” when you try to install or update device drivers. Driver Signing is the process of associating a digital signature with a driver package. Digital signatures are used in Windows device installations to verify the identity of the vendor providing the driver packages as well as to verify the integrity of the driver packages. All the drivers you usually install on your PC from Windows Update, Original Equipment Manufacturers, or some other third-party driver download software and so on must be verified digitally by Microsoft through the digital signature. A digital signature is an electronic security mark that verifies the publisher for the driver and all the relevant information related to it. That’s why Windows won’t run a driver if it isn’t certified by Microsoft, be it a 32-bit or 64-bit system – this is called the Driver Signature Enforcement. The only Kernel-mode drivers that Windows 10 will load are the ones that are digitally signed by the Dev Portal. However, the changes only affect the new installations of the operating system with Secure Boot on while the non-upgraded fresh installations would require drivers that are signed by Microsoft. The “Windows requires a digitally signed driver” error indicates that the driver you are trying to update or install hasn’t been signed digitally by the issuing authority, preventing you from installing or updating it. To resolve this issue, you can try to update the drivers directly from the manufacturer’s site. You could also disable driver signing via Group Policy Editor.

Option 1 – Update the device drivers directly from the manufacturer’s site

The reason why you’re getting the “Windows requires a digitally signed driver” error in the first place is that you might have downloaded the drivers from external media. It could also be that the drivers didn’t update for some time now and the issuing authority changed its policies. Thus, you can try to update the drivers straight from the manufacturer’s website and install them. If this option didn’t work, then you’ll have to disable the driver signing or its recognition in Windows 10. Keep in mind that doing so is not advisable if you have to use the concerned driver.

Option 2 – Disable driver signing via Group Policy Editor

• Tap the Win + R keys to open the Run utility and type “gpedit.msc” in the field and tap Enter to open the Group Policy Editor.
• After that, navigate to this policy setting: User configuration > Administrative templates > System > Driver installation
• Next, double click on the “Code signing for device drivers” entry located on the right pane to open its properties where you’ll see the following description:

“This setting determines how the system responds when a user tries to install device driver files that are not digitally signed. It establishes the least secure response permitted on the systems of users in the group. Users can use the System in Control Panel to select a more secure setting, but when this setting is enabled, the system does not implement any setting less secure than the one the setting established. When you enable this setting, use the drop-down box to specify the desired response. “Ignore” directs the system to proceed with the installation even if it includes unsigned files. “Warn” notifies the user that files are not digitally signed and lets the user decide whether to stop or to proceed with the installation and whether to permit unsigned files to be installed. “Warn” is the default. “Block” directs the system to refuse to install unsigned files. As a result, the installation stops, and none of the files in the driver package are installed. To change driver file security without specifying a setting, use System in Control Panel. Right-click My Computer, click Properties, click the Hardware tab, and then click the Driver Signing button.”

• Now select the radio button for “Enabled” and select Ignore from the drop-down menu under “When Windows detects a driver file without a digital signature”.
• Then click on the Apply and OK buttons to save the changes made. This will get rid of the “Windows requires a digitally signed driver” error but take note that this will also make your system less secure.

If you are browsing the web but suddenly encountered the ERR_BLOCKED_BY_CLIENT error on your Chrome browser in Windows 10, read on as this post will guide you in fixing this problem. This kind of error has already been reported by a number of Chrome users and it seems that the problem has something to do with a plugin or extension. Here’s the exact content of the error:

“This webpage was blocked by an extension (ERR_BLOCKED_BY_CLIENT)”

This kind of error, as pointed out, could be caused by an extension or plugin on Chrome that is blocking the web page. It is also possible that the version of Chrome is obsolete or that there could be more than 100 bookmarks in the Bookmark Manager. Before you troubleshoot the problem, make sure that you download the latest version of Google Chrome and see if it fixes the error. If it didn’t, then you can try opening a web page in Incognito Mode or disable and remove the extension that’s causing the problem. You could also try to remove any surplus bookmarks.

Option 1 – Try to open the web page in Incognito Mode

The first thing you can do to fix the problem is to try opening the web page in Incognito Mode. When your browser is in this mode, it will work without extensions. This would help in fixing the problem especially if it was caused by some extension or toolbar in your browser. All you have to do is open any web page in Chrome and tap the Ctrl + Shift + N key combination to open a window in Incognito Mode.

Option 2 – Try to disable and get rid of the problematic extension

After you’ve isolated the problem and have determined that an extension is the one that’s causing it, then the next thing you have to do is to disable or get rid of that extension.

Option 3 – Try removing surplus bookmarks

If your Chrome browser is already supporting more than 100 bookmarks, you might want to consider deleting them as it could also be one of the reasons why you’re getting the ERR_BLOCKED_BY_CLIENT error. To remove these bookmarks, just open the bookmark library by typing this address “chrome://bookmarks/” in the address bar of Chrome and tap Enter and press Shift and then select the surplus bookmarks by using the arrow keys. After that, click Delete to get rid of them.

Option 4 – Try clearing browser data

There are times when some data in the browser is conflicting with the loading of the website and triggers errors like ERR_BLOCKED_BY_CLIENT. And so you can try to clear your browser’s data. This might be a very basic solution but oftentimes it works in fixing this kind of error in Google Chrome. Follow the steps below to clear the data in your browser.

• Open your Google Chrome browser.
• After that, tap the Ctrl + H keys. Doing so will open a new panel that allows you to delete the browsing history and other data in your browser.

Building your own custom PC system can be one of the greatest things you can do to your budget. Instead of going for a rebuild, we will go into detail about why building your own PC is a much better option. Also, note that if you do not possess enough technical knowledge about a topic there are plenty of stores that will offer you advice on components and after all, you can always get help from a friend.

So without further diversion from the topic, let us explore all the benefits of building a custom computer.

Building a custom PC is cheaper

At the first look, this statement does not feel right since when you look at the prebuilt systems you get a feeling that it is much cheaper than do it yourself variant and although CPU and GPU seem like a great deal I beg you to look under the hood on other components. Usually to lower price compromise would be made on other crucial components like SD or power supply, a PC case, or motherboard so even if you have a good CPU and GPU that will not matter much since other components would not be able to catch up with them. After all, prebuild computers will need to pay people who are building them and there is no way that will be cheaper if you just plain went and bought the same components yourself and install them.

When you are in control in choosing each component there is not only being cheaper online, it is flexibility with building itself. You choose which components you want to be stronger and which to be normal. Also, you can choose the exact model of the given component leaving you more in control and open to future upgrades.

More flexibility

Also, it may sound irrelevant but when building your own custom PC you can also choose which company you would like to purchase for each model, yes considering the CPU it is AMD or Intel but when you are buying a case, SSD, GPU, and other components choosing the right company for your needs is also the thing that should not be overlooked.

You can customize it the way you want

Not really a quality argument but with a custom PC build, you can choose would you like that RGB component or not, you choose do you like white or black fans, and many more things. You really can place a personal stamp on the computer making it indeed a personal computer.

You choose OS and applications

When you buy an already prebuilt PC, usually it comes with some sort of OS on it, sometimes it is freedos, Linux and sometimes it is Windows Home. When you get your hands dirty you can place whichever system you want on it and install applications that you use and know and some preinstalled typical apps.

Error code 0x8007007b - What is it?

Error code 0x8007007b will present itself when Windows users are trying to activate Windows. You may try to activate it through the update and security option, but it is likely that you will receive the same error code. Error code 0x8007007b may be presented when Windows 7 and Windows 8.1 users try to upgrade and activate Windows 10 on their computer.

Common symptoms include:

• An error message will display that says Windows cannot be activated. The KMS host cannot be located in the DNS, please have the system administrator verify that the KMS is published correctly in DNS.
• Error 0x8007007b will be displayed, stating that the file or directory name or the volume label syntax is not correct.

Solution

Error Causes

There are multiple causes for the user to see this error code, including if a user is using volume-licensed media while installing a number of various Windows operating systems. This error may also be caused because the activation wizard cannot connect to a KMS host computer. It is likely that if the user has a volume-licensed form of media, they were likely given a MAK (multiple activation keys).

Further Information and Manual Repair

There are several ways to go about repairing error code 0x8007007b. It is important to try all of the methods, but if it is too difficult or you do not know what you are doing, please do contact a Windows repair technician. They will likely be able to fix the problem with ease.

Method One: Instead of KMS activation, use a Multiple Key Activation

When KMS activation is not used, and when there is not a KMS server, the product key type should then be changed to a MAK. For MSDN (Microsoft Developer Network) or TechNet, the SKUs that are listed on the media are generally volume-licensed media, and that means that the product key that is supplied is a Multiple Activation Key.

To change the KMS to a MAK, click Start, All Programs, Accessories, and then right-click on Command Prompt. Click Run as Administrator. If prompted for a password or confirmation, enter it now.

When the command prompt opens, type in the following command, and press enter after:

slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx (these x's are representative of the MAK product key).

Method Two

While on the desktop, press the Windows key and R. The Run window should appear, and then you should enter the following command: Slui 3. Press Enter and then wait for the window to appear. This window will ask for the operating system activation product key. Enter the product key and then press the Activate button. Reboot the computer. Now the Error Code 0x8007007b should be gone.

Method Three

Open the Command Prompt with access as administrator as mentioned previously. Enter the following command: sfc /scannow. The command will then complete its task. This will take a good bit of time, so leave the computer to do its work. The sfc must finish the scan. When the scan has finished, reboot the computer. Now you can check for activation. The error code should be gone.

Method Four: When the client can't locate a KMS host on the network to complete activation

This method for correction should be used when the network does have a KMS host computer setup, and the client is not able to locate the KMS host on the network to complete activation.

To verify that the computer does in fact have the KMS host installed. Click Start, All Programs, Accessories, and then right-click on Command Prompt. Run as administrator. If you are now prompted to enter a password or confirmation, do so. When the command prompt box comes up, type in the following command, and then press Enter: nxlookup -type=all_vlmcs._tcp>kms.txt

The command will generate a file, open this KMS file. The file will contain one or more entries. As a default, the KMS host server will dynamically register a DNS SRV server evidence once every 24 hours. In order to check the registry to ensure that this is happening, follow these steps:

• Click Start, type in regedit, and then press Enter.
• Locate the key HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionSL and then click on it.
• The DisableDnsPublishing subkey should be present and have a value of 1. If it is missing, create a DWORD value by right clicking DisableDnsPublishing, click Modify, in the Value Data box type in 0, and then click Okay.

Method Five: Use An Automated Tool

If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and install a powerful automated tool.

In the latest Windows 11 fiasco, it is reported that the operating system is slowing down some SSD drives. Good thing is that it does not affect all of SSD on the market but the ones which it is affecting can see even a 45% of speed drop. Microsoft has not published a solution to this issue, but users point out two potential problems. The first is a security mechanism based on disk virtualization, which is supposed to slow down the performance of SSDs. The second, in turn, is related to the place of installation of Windows 11 – users indicate that if the performance test is performed on a medium with no files associated with the system, its performance results are similar to the parameters given by the manufacturer. Transfer speeds were to be slightly improved with the latest Windows 11 update 22000.348. However, users are still waiting for a solution to the problem that significantly reduces the efficiency of SSD media.

More information

The details described leading to speculation that the problem could be related to drivers that Microsoft is providing. On further tests, all Nvme drives that use the Microsoft driver have this problem, but Intel 905P, which has its own driver provided by Intel, is working at full power,”.

Upgrading your computer from Windows 7 or Windows 8 to Windows 10 or even upgrading Windows 10 to a new version is not that simple. The setup initially checks for all the drivers and other software utilities installed on your computer and verifies and blockages or upgrade or upgrade blocks with respect to any of those drivers or any of those software utilities regardless if you use the Windows 10 ISO or the Windows 10 Upgrade Assistant. One of these common errors, when you upgrade or update your computer, is the “The Display is not compatible with Windows 10” error. This kind of Windows Upgrade error is related to the compatibility of the Graphics Driver installed in your computer. But worry not for this post will guide you in fixing this problem. The “The display is not compatible with Windows 10” error has the same workarounds as the following errors:

• These devices aren’t fully compatible with Windows 10.
• The display is not compatible with Windows 10. Check with the manufacturer for support.
• The display manufacturer hasn’t made your display compatible with Windows 10. Check with the manufacturer for support.

To resolve this Windows Upgrade error, here are some suggestions that could help:

Option 1 – Check for incompatible drivers in your computer

• Open the Device Manager from the WinX Menu.
• Then expand the list for Display Adapters.
• Next, right-click on the NVIDIA Graphics Card list and select Enable.
• After that, right-click on it again and click on the “Update Driver Software…” option.
• After doing so, a new window will appear and from there, click on the “Search automatically for updated driver software” option.
• Then check if Windows is now able to detect your Graphics Card as well as the latest driver for it. If not, proceed to the next step.
• Right-click on the driver again and click on the “Update Driver Software…” option.
• Now click on the Browse my computer for driver software option and then click on Let me pick from a list of device drivers on my computer.
• Afterward, select a compatible driver for your computer named NVIDIA Graphics Card and then proceed.
• Wait for the whole process to be completed and restart your computer to successfully apply the changes made.

Option 2 – Get the latest version of Graphics drivers from the manufacturer’s website

In case you don’t know the manufacturer of the Graphics Processing Unit or GPU of your computer, you need to check first. They’re usually NVIDIA, Intel, or AMD. So if your computer’s Graphics Processing Unit is manufactured by NVIDIA, you need to get the latest version from their official website.

Option 3 – Try to install the latest Graphics driver in Compatibility Mode

If you’re not able to install the Graphics drivers you’ve downloaded, you can try installing them again but this time using Compatibility mode. Follow the steps below to do so:

• You need to download the driver and place it on your desktop.
• After that, right-click on it and select Properties.
• Next, switch to the Compatibility tab where you should see two options:
  • Compatibility troubleshooter, and let Windows figure out what works best for you. If it fails, follow the next.
  • Manually choose the version of Windows it was correctly working.
• You also have the option to change the DPI settings and see if that helps. Then click the Apply and OK buttons.
• Now right-click on the file and select the “Run as administrator” option to install. After that, you should now be able to change your screen aspect ratio to what you were using early on.

Note: If you have other programs that won’t work on the existing version of Windows, then make sure to run the program in a Compatibility mode.

Option 4 – Try to run the Program Compatibility Troubleshooter

You might also want to run the Program Compatibility Troubleshooter. This built-in troubleshooter is available in the Windows Update & Security section. From there, select Troubleshoot. This will find a list of programs for you and since you have already downloaded the driver files, just click on Not Listed located at the top of the program list. After that, browse and select the driver files and then let the program do its job.

It has been some time since the release of Diablo 2 resurrected and overall reception was pretty good. People are enjoying the old classic game in hi-def. resolution and with new and improved visuals. Sadly some server issues are present still until this day and somewhat spoil the experience for players. The greatest lag and server crashes are pinpointed to game-creating events. When a player creates a new online game, the server needs to pull a lot of details from the database and make a game, due to some legacy code present this process takes some time and it is demanding a bit on the server-side, and although code was optimized to cater to more modern approach some legacy code still remains. Another thing that was spotted to affect performance itself is player behavior, to be more specific, modern gamer behavior. Where players find good builds and runs on the internet and then go to farm-specific areas or bosses for loot or experience points, which in return boils down to making plenty and short runs that are made by creating games and after run eliminating them. Now pair that with the previous statement about legacy server and database code and you can add 1 and 1 and see how this might be an issue. A lot of short games over legacy code are placing games in a state it was not designed for back in 2001 and therefore we have issues. Sadly solutions without completely rewriting the whole code are not very promising and they include rate limiting, which will prevent players to create many games in succession in a short period of time and maybe even login queues to drop a load on servers. Blizzard reached to people in the whole company, even old diablo 2 developers to ask for advice and they say that they are working on solutions so they could lift limitations and have everything running fine.
