Today I logged in after the new update. (Oct 4th). Firefox was stuck in a loop for looking for updates. I went round and round, couldn't solve it, finally decided to reinstall. When I reinstalled it said I already had an installation and asked if I wanted to open the existing application and keep all my settings etc., or not. I tried opening the exiting application, but it kept looping back with the same question, not opening the existing application. I ultimately told it to start fresh, even though I knew I would lose all my configurations, addons, etc. I then spent quite a bit of time reconfiguring everything. I turned on synch and kept the synch key. I closed the application, reopened it, and it put me back to the original screen for installing afresh, asking if I want to open the existing application or start again and lose all my configurations and data. It wouldn't let me open the existing so I reinstalled and had to begin again. I don't know what to do.

I'm on OS 15.6.1 (24G90) lapbook pro, I think it's called

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!

I have an M1 Macbook Pro running macOS 15.5 (24F74). Often after booting up my laptop when Firefox launches it freezes. When I long press on the Firefox icon it says "Application is not responding".

I found this post: https://www.reddit.com/r/firefox/comments/1fi4p94/firefox_freezing_on_start_on_macos/ which mentions an incompatibility with Firefox and Adobe Creative Cloud. Sure enough, when I quit Creative Cloud Firefox starts successfully.

Anyone have any ideas of what's causing this?

Firefox hat während der Arbeit plötzlich abgebrochen, angeblich ein Update installiert - danach kam ein Fenster, wo ich neu starten oder abbrechen konnte - war allerdings eine Dauerschleife. Neu installieren will ich nicht, weil dann wieder mal alle Kennworte und Lesezeichen weg sind! Die Lösungen von Mozilla sind meistens unbrauchbar weil Firefox ja nicht startet !!!

i was able to download firefox. but now when i click on the icon to load up firefox it says couldn't load xpcom. what does that mean, what do i need to do to fix it?

Firefox keeps crashing on my laptop I've had it run very successfully on the same laptop the first time i installed it it crashed the same way it does now but one day it randomly worked and continued working for about 9 months however at some point it crashed and i deleted it and reinstalled many times at best i have downloaded it and have managed it to run for about 10 minutes then closed and failed to load properly now it fails to launch completely at worst it doesnt run at all .i have tryed downloading it from the microstoft store and your website this time i downloaded it from Microsoft please help!

I've only had the new laptop for 2 weeks, it was working OK (except for new Outlook and cannot revert to old when I try) and suddenly today, I can't access F/fox any way I try) Bing constantly hijacks Firefox when I try to load it; cannot re-set firefox as default from Bing page; attempts to re-set default from M/S Edge continually revert to Bing.

(I've been using firefox for over 20 years and DO NOT want to change.) Please help!!!!!

Please help!!!!!!!!!!!!!!!!

I'm getting the 'Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window' message. I've gone to the task manager and end tasks. Then try to delete parent.lock in Firefox profiles in appdata. Then I get this message... The action can't be completed because the file is open in Firefox. Can you please help me with this problem.
