I-Firefox Community Forum

I have been battling with Firefox for a bit now with this 'helper tool' download. Every single update it requests access, which is has, and then won't actually open Firefox. I have to uninstall and reinstall each time to get some level of functionality back.

Checking online this isn't a problem isolated to my own computer, but aside from getting the pro version, there were no great solutions.

Can this issue please be fixed?

Whenever I try to open firefox it automatically opens google chrome, I haven’t used chrome for over a year and i’ve set firefox as my default app for everything. I double checked the shortcut to make sure it’s going to the right place and it is. and i’ve tried deleting Chrome via Revo Uninstaller but the issue persists.

this wasn’t happening 5 minutes ago and i can’t exactly think of a reason for the change.

My Surface Laptop 7 w/ SnapDragon Elite's Firefox installation started crashing this morning immediately after rebooting to complete some Windows updates. I have attempted starting Firefox in Maintenance mode, Uninstalled and reinstalled and I still get the crash reporter. Refreshing Firefox at the uninstall process does not fix it.

I'm running Windows 11 Enterprise edition, fully patched w/ Firefox 146.0.

The 4 Windows updates that were installed:

Uninstalled KB5072033 Uninstalled KB5070311 Cannot be uninstalled KB5072641 Cannot be uninstalled KB5071142

Still didn't fix the problem.

These are the recent crash reports:

Any help is appreciated!

Firefox is already running old Firefox must be closed. I have tried everything in the help menu. delete parent.lock , restarting etc. nothing is working. I can create new profile but i cant find any toolbar, bookmarks etc please help

When I turn on my Mac and click the Firefox browser icon, it will not load. It hangs. I get a "not responding" message and have to "force quit," again and again until FINALLY it loads, after five or more failed attempts. This does not happen with Firefox on my laptop, only my Mac. Both Firefox and my Mac are up to date. Why is this happening? Please help. It happens every day when I try to load the browser. I am about to give up and move to Safari. Relatedly, anyone know if it's possible to export all my bookmarks from Firefox to Safari?

Firefox does not start automatically when Windows 11 starts. When I do start it manually, then a small rectangle appears on the screen in the upper left corner of the screen!

Please address issues.

I try hard to use firefox in headless mode for a python selenium project in freebsd. But firefox complains about GPUs and the absense of a X-Server, but this is a headless mode and crashes with a segmentation fault. Why does it want a GPU and X-Server in headless mode? Does not make sense.

The output when i try to start is : " firefox --headless

Can anyone help me? Best regards Josef

since 3 days, after initiation of the Firefox the empty page appears with order to close firefox. A have reinstalled the new version several times withour anu change in the program behaviour

I’m suddenly unable to open Mozilla Firefox at all on my Windows 11 Pro (version 25H2) Surface Laptop. The browser never launches - every attempt immediately crashes and opens the Firefox Crash Reporter.

I tried uninstalling and reinstalling a fresh copy of Firefox (and removing the old application files, though the original Firefox program folder has 13 .tmp files inside a “tobedeleted” folder that I can’t delete), but the issue persists. When I try to install or uninstall Firefox, I get the same behavior: Firefox never opens, and I end up with multiple instances of the Crash Reporter popping up instantly.

Tried renaming firefox.exe as well to no avail. Chrome and Edge are working fine.

As the title says Firefox has stopped working for Mac a few days ago after the update. all I get when I open it is a blank grey box. My software is up to date and I have uninstalled and reinstalled Firefox multiple times, nothing worked. is there any way to fix this other than waiting for Firefox to update again? I just want to bring this to Firefox's attention so it can be fixed, I like Firefox it's my go-to browser to use.

A few days ago (December 17th or so), Firefox just up and stopped loading altogether. I’m trying everything I can find, but to no avail. The internet itself is working fine. This is the message I’m getting (see attached).

I’m getting desperate, I can only do so much on my phone!

Thanks, Alsie

Firefox 146.0.1 crashes every time upon launch (basically fails to launch), even in troubleshooting mode, with exception code 0xc0000005. Prior to today, it was working fine. Windows does not show any updates made over the last couple of days. I am on Windows 11 25H2, and I'm current with updates. Chrome works. Edge works. I logged on to the same computer as a different user (different profile folder in the user AppData folder) and Firefox still does not work. I tried to refresh Firefox and that did not resolve the issue. I tried to uninstall and reinstall Firefox and that did not resolve the issue. I tried to run DISM and SCANNOW and that did not resolve the issue. No issues are detected with a virus scan. I am stumped - please help!

Every time i would open the app, it would crash immediately. I uninstalled and reinstalled, had the same issue. Recently updated to Win11. Reported each time but can't get into the app so don't know what the error is.

When I open Firefox in Windows 11 a small window appears that reads, "Firefox Couldn't load XPCOM. I have not found any solutions to stop this that work. Will Mozilla fix this?
