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

Hello,

I have the latest version (140) of Firefox installed on a Windows 11 laptop with the latest Windows updates. It works fine for my user (who, BTW, has admin privileges) but it won't even start for my wife's Windows user. To be precise, "won't start" means that when you try to launch it it sometimes looks like it's trying to create a window but immediately closes it with no error messages, no crash reports, no logs, nothing at all. It won't even start from the Run menu with any command line flag like -p, -ProfileManager or even -safe-mode, I tried all of them.

Other things I've tried: 1) Check the Windows event logs. Nothing. 2) Run sfc /scannow to check for corrupt system files. 3) Uninstall Firefox, delete the Program Files\Mozilla Firefox folder, and re-install it. 4) Move the entire Firefox folder inside %appdata% to a temporary folder outside users. Firefox recreates it, creates 2 new profiles and dies silently again! 5) ...and a lot of other things that I read online and do not remember anymore.

At this point I'm at a loss and I'm an IT guy. Of course I have no idea how this happened, the browser used to work fine up until a week ago or so. Other software that might interfere is Malwarebytes, but it works fine for my user, so... 🤷🏻‍♂️

Thanks in advance for any ideas.

After my pc has been on for a while, seemingly random duration, Im not able to open firefox anymore. For example if clicking on a link in discord, or if I close the browser and want to open it again. I've tried refreshing and reinstalling but that didn't help.

My copy of Firefox, installed on a MacBook Air, has suddenly decided not to open. When I click the icon I see a brief flicker on the screen but the application does not open. Version is 140.0.4. Has anyone else experienced this?

Application error: a client-side exception has occurred while loading (see the browser console for more information).

where is the browser console? how do i fix it never had an issue with until the last two days?

starting the computer I receive following message: C:ß\users\....\AppData\Roaming\Mozilla\Firefox\Profiles\ibp4oc3n.default-release\search\json.mozlz4

can notbe opened

whatshall I do?

Thank you! Anne

There always seem to be daily issues, "Mozilla Not Responding". We clear out Cookies, Cache, history, etc. throughout the day. We've had to shut it down and restart the computer. Oftentimes, the system just shuts down.

For the last few weeks, we have an unknown popup from Mozilla, "Unable to load XP.com". Not sure what this may be or why this popup suddenly started. We close it and pops up periodically several times in a day. I am attaching a screenshot of the image.

Thanks
