פורום התמיכה של Firefox

I have chosen to not auto-update the browser because it interferes with my work. The precise setting is called "Allow Firefox to" "Check for updates but let you choose to install them" (screenshot attached). However, this setting is not honoured. Every month, the browser auto-updates and forces a browser restart for me to continue working (screenshot attached). For 126->127, there was in fact no notification to update and the update happened automatically in the background with a restart forced upon me. What's the point of having this setting if it's not going to be honoured?

I always had one version of Firefox installed. I regularly update the software via Help >> About Still, after every update, I am getting multiple versions of Firefox listed at [Settings/Installed Apps] and [Control Panel/Uninstall or remove apps] on my Win11 23H2 22631.3593 (screenshot attached).

In order to get rid of outdated items from the list, I need to reinstall Firefox completely, but the same thing is happening with every update of Firefox.

Is there a way to resolve this and why is this happening?

I restarted my Windows 11 laptop and got error message about user profile. Restarted again and looks like it was corrupted so deleted my my user profile and Firefox config and bookmarks are gone!

Still have all the files just a new user profile and the old one is gone?

Any help how to get Firefox bookmarks back would be much appreciated

I cannot download any files or any adons through firefox. I have tried every single troubleshooting method in the "What to do if you can't download or save files" article I have restarted my computer, I have refreshed firefox, I have reinstalled firefox TWICE, I have turned off my firewall and tried downloading a file, I have changed the wifi im connected to, I can download files on internet explorer just fine, I have tried a new profile, I have scanned my device for viruses (theres none), I have no idea what the troubleshooting mode is supposed to do because I cannot download files in that either. I currently have no ad-ons installed because of the refresh I dont know what else to do and why is my firefox doing this, it started yesterday.

Hi there,

On the 23. of Mai I first noticed that I am unable to download any files whatsoever. I tried downloading .exe files and also a .csv file. When I try to download one of these files it appears in the downloads window but immediately goes to the status "Failed". Any retry fails as well.

The same thing goes for extensions. I cannot download any extensions or plugins using my Firefox browser. Since I reinstalled Firefox I can now also not use Plex because Firefox can't install the required plugins.

I will attach screenshots of all the errors I get.

All of the above worked when I tried it on the Edge browser.

Firefox version: 126.0 Windows 11

Things I have tried to fix the issue:

• Use the network connection from my phone instead of my home network
• Disable firewall and windows defender
• Reinstall Firefox
• Refresh Firefox
• Downgrade to version 125.0.1 and 122.0
• Reset router to factory settings
• Flush dns
• Restart PC
• Manually delete profile folder
• Delete temp files
• Change download destination
• Disable "Block dangerous and deceptive content"
• Troubleshoot Mode

Is Firefox using some other temporary folder for downloads?

Any ideas on how to fix this issue would be appreciated.

Thank you.

I am in the process of migrating to a new Windows 11 PC. I am a long-time user of Firefox and have version 126.0 - 64 bit on my old PC. On my new PC I apparently downloaded it from the Microsoft Store during all my software installs. That version shows as "Windows MSIX Package Mozilla – MSIX – 1.0”

Are there differences between the 2 versions and should I do anything such as reinstalling from Mozilla?

Thanks, BillT
