My Firefox can only be shut down by TaskManager, or by clicking on the three horizontal bars and then dropping to exit.

So I can't close any single tab 'without closing them all', that's the real annoyance. I also can't close any individual windows I opened instead of a new tab, without closing all tabs and windows. Finally the classic windows ALT+F4 closure that's built into Windows doesn't close Firefox, and if it did I suspect ALT+F4 would close them all. Bottom line Firefox is seriously close-resistant.

What precipitated this was I allowed a previous Firefox update to download-install, and it tanked my performance, I figured your team would fix that issue, but in the meantime what I did was uninstall that version and reinstall the version I had been running before that update. Tilt! That action resulted in the close windows or tabs problem.

Summary: I am using the latest version now, but with it came this "can't close any individual tab without closing them all, and can only close even then except by Taskmanager or by clicking the 3 horizontal bars then dropping to Exit which also closes all Firefox tabs and Windows. This problem has surfaced before in this support, and none of the solutions worked, probably because I got to this place uniquely. I did read before submitting this.

I have 3 laptops all running windows 10 or 11. These all share a docking station giving access to an extended display, keyboard etc. All laptops run fine with the docking station except for one issue with the newest laptop... The screen resolution, only on firefox on the one laptop, (everything else is fine) is completly out of whack. I have tried the zoom function but no luck. I have trawled the internet but all the solutions are from 10+ years ago and refer to different versions of firefox and windows. I am not a computer geek so please dumb down any advice.

Whenever I get a link whether in an email from a verified sender or from using a site like Amazon, clicking on a link always results in "Hmm. We’re having trouble finding that site." This has happened ever since loading the most recent version of Firefox (124.0.2) and it is very, very frustrating. What is causing this? Even in "safe" mode this occurs. Please rectify this situation. I do not want to have to change browsers after more than 20 years with Firefox.

Sometimes all add-ons / extensions break randomly and are disabled (the icon of the extensions is also broken under "Manage Your Extensions").

The extensions are visible under "about:addons", but the slider is turned off and the icon in front of each extension is broken / empty.

It seems that deleting these 2 files- compatibility.ini and extensions.json inside the firefox profile folder, usually fixes the issue. Only these 2 files though, don't delete anything else.

No need to mess around with the ff profiles or anything else, just deleting those 2 files and restarting the firefox usually fixes the issue with the "unregistered" addons.

This thread is for the search function, as I found some VERY old and outdated suggestions for the aforementioned issue using the search function.

I wonder what causes the extensions to "unregister" randomly.

My Firefox recently updated to version 124.0.2. Afterwards my taskbar shortcut broke, so I pinned a new one manually (right-clicked Firefox in start menu > open file location.) When I opened Firefox it had reset the primary profile to be default, so I changed it back to my BetterFox profile. Since then I've run into several oddities, such as Firefox crashing when it's running in the background, getting an error saying "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window," when I try to open it, invisible shortcuts in my taskbar(see image) and my bookmark visibility resetting from always to only in new tab every time I start up Firefox. Please help me.

Hi, i just got a new laptop (Asus Zephryus G16, 2560 x 1600 screen) and after installing Firefox there is a thin white border to the left of the screen when running in fit screen. This problem is not present when in a windowed mode or in F11 full screen.

I tried updating the Intel Arc drivers but this did not fix the problem. Changing to compatibility mode also did not fix te problem.

PS: in the uploaded screenshots it is quite dificult to see the white line(because the background is also white), but when the image is viewed in a new tab it is visible.

Thanks

Installation aborted because the add-on appears to be corrupt.

I am using Firefox Developper Edition, with extensions.langpacks.signatures.required set to false.

This addon, after download, installs fine as a temporary addon.

How can I install it permanently?

On the page listing passwords, it was possible to sort them by "Alerts".

In settings, there is an option to enable checking the vulnerable passwords: https://support.mozilla.org/en-US/kb/firefox-password-manager-alerts-breached-websites

On my other laptop using Firefox v121, the alerts are properly displayed. But on my second laptop using Firefox v124, the alerts are gone. I can't sort password by "Alerts", the option isn't there. Both laptops share the same Firefox account and have password synchronized between each other.

Obviously, I ticked the "Show alerts about passwords for breached websites" box in the settings but it looks like it does not nothing. I also checked in "about:config" and everything seems good.

Is this feature gone?
