Firefox Community Forum

Recently updated to Windows 11 after Windows 10 stopped getting supported. After putting down several smaller issues on my own, I can encountered something I cannot fix on my own. Currently, I cannot detach, reattach, move tabs (With the exception of moving tabs with the right click menu). I could do all of these on Windows 10. I have already tried the browser.tabs.allowTabDetach setting in about:config to no success. I am starting to suspect it is a problem with windows versus a problem with Firefox because of an earlier bug where I couldn't move the windows entirely without enabling the Snap Windows function in my settings.

I recently updated to 147.0.1, and now it seems I can no longer access word/excel/powerpoint files for online editing. I have already tried clearing cookies, disabling adblockers, disabling tracking protection, running in a private window, all the way down to completely reinstalling Firefox 147 fresh. This has persisted for roughly a week, so it does not seem to be an issue with my own network connection, nor with Microsoft's services, nor my files specifically since I can edit the files online from my PC at work. The error message specifically reads:

We can't connect to the server at usc-excel.officeapps.live.com (or usc-word-edit.officeapps.live.com or usc-powerpoint.officeapps.live.com, respectively).

I could previously access these files to edit when I was still on Firefox 146, so I'm guessing it's something going on with 147. Has anyone encountered similar issues with Web Office apps, and perhaps found a resolution?

Hello, I am still running an old WIn 7 media center because I have applications I need that are no longer supported elsewhere. Firefox ESR has been working just fine up until the most recent update - which repeatedly fails to install each time I start Firefox. Is there a location where this update resides? If so may I know this location and procedure to eliminate this errant update? Thanks!

Through extensive troubleshooting, I am unable to get firefox to open at all.

I've done a full uninstall, cleaned all user directories, program files / x86, program data, appdata roaming and local, etc. I used the Microsoft uninstaller and even Revo Uninstaller to remove everything related to Firefox, did a restart and reinstall of the latest one and it still won't launch.

Firefox was previously working until a reboot occurred and now it won't launch.

Firefox 32 bit seems to work when installed, and running Firefox as an admin previously worked but no it no longer does.

I looked at the following articles: - https://support.mozilla.org/en-US/kb/firefox-wont-start-find-solutions - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles - https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles#w_start-the-profile-manager-when-firefox-is-closed

There's no malware on this machine (business EDR on it, even disabled it as a test and it still didn't open).

I was able to launch the profile manager but now I am unable to as the processes launch in task manager and then within 5 seconds they close.

Firefox is not running in the background for any user (I'm the only one logged in after a reboot as well)

I'm unable to open in troubleshoot mode either. Tried run as and admin cmd "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode

Ran SFC / scannow / DISM restore health commands as well and both came back fine / no integrity violations

Hi, I don't understand why I can't access the Accor Hotels website using my preferred browser, Firefox. I'm using an iMac with OS Catalina v 10.15.7 and Firefox 147.0.1 (64 bit)

I can access the site using Chrome. Chrome version is 'This computer is using macOS 10.15. Learn more Version 128.0.6613.138 (Official Build) (x86_64)'

I've checked every Firefox setting I can think of, passwords etc. but the site freezes. Please see attached screenshot. Accor tech support say they have no problem at their end.

Other sites all seem to work ok.

Any ideas pleas on why just this website and how I can access it without having to swap browser?

I noticed of late that the Firefox Taskbar icon is no longer recognizable on the Windows 11 Taskbar! It is no longer a circle showing a fox but is a rectangle with a dark square like thing in the middle with very tiny dark spots in lighter areas. How can I get the original icon back that is recognizable as Firefox?

Thanks

Same Problem as here but thread is archived: https://support.mozilla.org/en-US/questions/1465988

It has always worked great until now, but it seems that it no longer works with Firefox 147.0.1. Does anyone have any idea how to fix this?
