I updated my Mac to macOS Golden Gate. Tried to update Firefox from a non-admin account. It failed. Went to admin account, deleted Firefox and reinstalled from a new dmg download. All fine in the admin account. But the non-admin account (where I work day to day) won't even launch a Firefox window. It asks for admin access to install a helper. I can't see why it needs this but have given it via username and password, but it still doesn't launch. The dock icon says "Running in Background" when I hover over Firefox and the icon bounces. But no browser window

I had been using the Mozilla Firefox VPN for a few weeks, but now it will not launch. I sign in without a problem but when I click on the VPN icon on the toolbar, nothing happens. I just get the pop-up to try the VPN and "Get Started" (see attachment).

Please advise.

Hello,

Recently, (past month or so) I have had difficulty opening Firefox on my PC. Found suggestion of renaming the .exe which did work, but now it will not open AT ALL. Uninstalled, and re-installed. nothing. Renamed .exe. Nothing. It will OPEN as admin, but cannot access any settings or browse. I am at a loss, and really do not want to go back to Chrome.

Previously attempted uninstalling ESET antivirus and Defender, and still would not open.

Thank you!

- Had 3 windows open with numerous tabs and tab groups - Firefox sync was enabled, as well as a 2-3 plugins AFAIK - Version installed is latest as of this writing 139.0.4 - Initial crash caused by opening and quickly closing (IF that succeeded before crash) a onedrive share link - Cannot start firefox any more, also not in safe mode - the only thing that works is launching it with a fresh profile.

The report ID is bp-a8c824fc-a7fb-4290-a72b-b63160250620

Ideally I can resolve this without needing to refresh or start over with a new profile

Firefox keeps crashing, or better doesnt even open. In Task Maneger on my Windows 11 System I didnt even see the task preformed. So I tried to uninstall Firefox and reinstall Firefox, still the same Problem. I tried to refresh Firefox but it was no use. Sometimes for a brief moment of time a small window opens with the Firefox logo, for two seconds I can read the word Firefox Troubleshoot but it closes instantly. I need Firefox as my Browser and would like to have it back in use as soon as possible. Thank you for your help LH

I cannot get into Firefox due to an error message that keeps coming up. Your Firefox profile cannot be loaded. It may be missing or inaccessible.

I have tried deleting and reinstalling it, but it didn't really uninstall completely. I have tried a few suggestions from online, which didn't work. I also tried right clicking on the Firefox symbol and went into some of the different options, but nothing worked for me.

After installing Firefox on a new Windows 11 computer, when I click on the Desktop icon, a Firefox window opens but it doesn't open previous Tabs and the Application menus does not work. I can open new Tabs though and it downloads websites. If I click on the Firefox icon on the Windows Taskbar, Firefox operates normally.

Why doesn't the Desktop icon start Firefox so it works correctly?

Thanks

Hello! I am an avid user of firefox (especially with adblockers) on a windows 11 PC. Unfortunately, I have recently been experiencing an issue where when I attempt to open firefox, a window will open for a split second before instantly closing again. My PC is up to date, I have tried refreshing firefox and doing a clean install, but cannot seem to overcome the issue, or even open it in safe mode. Does anyone have any advice? Many thanks in advance!
