Firefox is no longer working on my new Surface Pro. I tried to open a new session and received the following error: BuildID: 20251205151434 CrashTime: 1765375923 InstallTime: 1765289759 ModuleSignatureInfo: {"Mozilla Corporation":["firefox.exe","mozglue.dll"],"Microsoft Corporation":["msvcp140.dll","VCRUNTIME140.dll"],"Microsoft Windows":["CRYPTBASE.dll","crypt32.dll","fltLib.dll","version.dll","bcrypt.dll","ucrtbase.dll","KERNELBASE.dll","bcryptPrimitives.dll","kernel32.dll","advapi32.dll","rpcrt4.dll","sechost.dll","msvcrt.dll","ntdll.dll"],"SentinelOne Inc.":["InProcessClient64.dll"]} ProductID: {ec8030f7-c20a-464f-9b0e-13a3a9e97384} ProductName: Firefox ReleaseChannel: release StartupTime: 1765375923 SubmittedFrom: Client Throttleable: 1 UptimeTS: 0.0 Vendor: Mozilla Version: 146.0 WindowsErrorReporting: 1 This report also contains technical information about the state of the application when it crashed.

I have uninstalled and re-installed several times and even the downloader throws this error once it finishes. I simply can no longer use the browser. This is a huge inconvenience since I saved so many links for my work. Please help.

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.

I think my account had been hacked,,, I icon have been faded out on my mack, and it says: You can't open this application FireFox, because it may be damaged or incomplete

I have tried all the troubleshooting steps of uninstalling, reinstalling and backing up my profile but on every machine after one session or one time instance and if I have to close Firefox or restart my workstation, I can no longer launch Firefox. It leads me to believe there is some kind of profile issue or corruption with my account but for months I've been battling this issue and can not resolve it. I do remember getting some Firefox window showing the Profile option or Create Profile and I believe nothing was selected. I proceeded to select the Profile on the left and it seems after that is when all the problems started to occur. If anyone has experienced this or can assist, I would greatly appreciate it.

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.

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

Hello,

The Firefox I was using was crushed entirely and lost all my passwords, bookmarks, etc. The app's folder is not accessible. Then I downloaded a new version, and when I tried to open the app, a dialogue box said Firefox was trying to install a helper. Cancel does not work, and the "OK" stops the opening. I have a Mac with an OS Sequoia 15.

I tried to transfer the json, place.., key4, etc by copying from the old information i have, but the system does not work.

Thank you for your needed help.

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

Hello, I have installed the latest Firefox on my Windows 11 desktop PC. I have created a shortcut to Firefox in the start menue Since a few week, I observed that I had to invoce Firefox twice in order to get is running once. The same happens if I double-click on firefox.exe in the intallation folder (C:\Program Files\Mozilla Firefox): After the first double-click, the windows activity circle appears for a few seconds and then dissapears again (without staring Firefox). After the second double-click, Firefox starts immediately.

I can repeat this several times.

• first double click > nothing happens
• second double click > Firefox starts
• closing Firefox
• third double click > nothing happens
• fourth double click > Firefox starts
• closing Firefox
• fifth/seventh/... double click > nothing happens
• sixth/eigth/.. double click > Firefox starts

I have no idea what might have gone wrong. Any suggestion from the community is appreciated. Best,

I'm a Mac user on desktop. Something happened to my Firefox about two weeks ago. I was able to bring up Firefox which had all my bookmarks, passwords, etc. What is different is that I can not bring up Firefox by hitting the icon in the dock. If Firefox is already up and I hit he icon, it will jump to the front. But not if it is sitting in the dock.

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?

Hello,

I updated Firefox on Mac and was prompted to install a helper and now Firefox will not run. I've tried several times. I uninstalled Firefox and tried to reinstall but when I try it doesn't work.

Thanks.

I have this message after returning from nightly version to the stable one: ``` Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox. ```
