Nearby Sharing is not working in Windows
Windows 10 has a lot of several useful features and one of them is the Nearby Sharing feature. You can access this feature by going to Start > Settings > System > Shared experiences. From there, switch on the Nearby Sharing option and select the folder where you want to download the files to. This feature is really useful as it allows you to share files. However, there were reports from a number of users recently stating that Nearby Sharing is not working on their Windows 10 computers. If you are one of the users facing this problem, you might want to try checking if the Windows 10 v1803 Update is installed on your computer or not. You could also try to check if Bluetooth supports low energy mode or you could also try bringing the device closer or check if the adapter has Bluetooth version 4.0 or later. For more information, refer to each one of the given options below.

Option 1 – Try checking if Windows 10 v1803 Update is installed

To check if the Windows 10 v1803 Update is installed on your computer, go to Start > Settings > System > About. From there, scroll down to the Windows specifications and check the Version. If it is 1803 or above, then the Nearby Sharing feature should be active on your computer. However, if you find that Windows 10 v1803 Update is not installed yet, then you need to update your computer to its latest version and then see if it fixes the problem or not.

Option 2 – Verify if Bluetooth supports low energy mode

Although low energy mode is not really necessary in using Nearby Sharing, there are some Bluetooth terminals that support low energy mode which makes a lot of difference. Thus, you need to check if Bluetooth in your computer supports low energy mode by following these steps:
  • Tap the Win + R keys to open the Run dialog box.
  • Next, type “devmgmt.msc” in the field and tap Enter to open the Device Manager.
  • After that, expand the list of Bluetooth adapters, and then right-click on your adapter and select Properties.
  • Go to the Details tab and select Bluetooth radio supports Low Energy Central Role from the drop-down menu and if its value says “<true>”, it means that your Bluetooth supports low energy mode, otherwise, it doesn’t.
  • If your Bluetooth does not support low energy mode, then you might want to consider purchasing an external one.

Option 3 – Try bringing the devices closer

Nearby Sharing might not work if your devices are not close enough. Thus, you need to bring your devices closer together and see if it fixes the problem. And when you do, make sure that Network Sharing is switched on for all the concerned devices.

Option 4 – Make sure that you’re using Bluetooth version 4.0 or later

For you to use the Nearby Sharing feature, you have to make sure that the adapter for all the concerned devices is using Bluetooth version 4.0 or later. So if one of the devices or if all the devices are not using this version or later versions, then you must buy an external Bluetooth adapter for you to enjoy the Nearby Sharing feature.

Custom widgets in Windows 11 later
windows custom widgetsOriginally Microsoft has imagined its widgets menu as Microsoft-only widgets but it seems that they have changed their mind. Due to the latest leak, it seems that Microsoft will open the widgets menu to 3rd party developers as well but at launch, it will be only official widgets. It was hinted that later widgets menu will be open to developers who want to bring their own stuff into it. Distribution, date, and technology that will need to be used in order to create your widget have not been discussed nor leaked at a given time but in some way, I am very glad that at least some customization will be in Windows 11. It is funny and amusing how some things that were in Windows Vista are getting back like glass design, round corners, and widgets. Let’s just hope Windows 11 will be a better Windows than Vista was.

Firefox shows wrong or no bookmark favicon
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.
