I-Firefox Community Forum

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?

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!

Here is what the message says: "Firefox is trying to install a new helper tool. Enter your password to allow this" I tried to install but Firefox won't open. Firefox icon just bounces around, I have to force quit to stop it. I DO NOT WANT THIS TOOL BUT I WANT TO USE FIREFOX. By the way this is sent from my other user, as the problem is on my admin. user and I can't open Firefox to do anything!

Today Firefox on my laptop will not open. There is a message (?from Google?) saying it is because cookies are switched off. I have not knowingly made any changes to cookie settings or installed any new features. A new Windows update installed recently (I am on Windows 11) and also a new version of Edge (although I never use Edge myself). The Google guidanc eon how to fix the situation only deals with Chrome. So how, please, can I get Firefox working again?

ich habe probleme firefox zu starten wenn ich den browser öffnen will erscheint die meldung das firefox nicht geöffnet werden kann weil er noch geöffnet ist obwohl er aber geschlossen ist ich habe schon versucht den laptop neuzustarten und Firefox neu zu installieren es kam immer die selbe meldung der laptop verwendet Windows 7

I have looked over this computer high and low for any profile files in every way recommended on this website. I can't find it, regardless of what I put into terminal or what settings I change. This was a problem before the update to tahoe too.

CCleaner automatic upgrade to "ccleaner 7" killed Firefox! No other changes to the SW or machine. This computer works great every day. Fully up to date with Microsoft. The "upgrade" that I did not ask for, lost my license and switched me to the "free version of CCleaner. I uninstalled it and started over from CCleaner website. Worked fine with old version. It upgraded itself again and now Firefox is dead. Microsoft Edge does open. I never use this. Thanks

This is the message that pops up when I try to open Firefox: [Window Title] C:\Users\Kurt\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar\Firefox.lnk

[Content] Windows cannot find 'C:\Users\Kurt\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned\TaskBar\Firefox.lnk'. Make sure you typed the name correctly, and then try again.

[OK]

Hello! Thank you for taking the request!

My firefox browser crashes repeatedly at startup, only showing the crash report window instead of opening the browser. When starting the browser using troubleshoot mode, it crashes too, showing the same result. After uninstalling and re-enstalling the latest version, the exact same problem continues.

I've scanned for viruses and checked the computer RAM and neither seems to be the problem.

The latest submitted crash report ID is bp-0917ab7e-e656-42ff-aa92-40b8c0251112⁩

I'm really grateful for your help, and looking forward to your reply!

I just installed Fedora KDE Plasma, and have been trying to launch Firefox, but it keeps completely freezing.

I have tried installing through snap, flatpak and fedoras database, most recently I installed from the tar.xz on the website, and tried launching in safe mode. All of these result in the same behavior.
