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. ```

Sometimes when I do a google search the results come up in a foreign language! I am in the USA and speak only english. Changing my preferences doesn't always maintain the fix.

Every so often for the past few days this "unfinished" program window has appeared on my pc on top of a normal Firefox window (see attached png). Does this have something to do with Firefox? I think the same thing appears when I first open Firefox, then it gets "filled in" and appears as a normal Firefox window. I am running Firefox 133.0.3 (64-bit) on Windows 10 Pro Version 22H2 build 19045.5247 Windows Feature Experience Pack 1000.19060.1000.0.

On one macOS Sonoma machine, Firefox launches very slowly and then crashes. On another Mac with the same macOS version, Firefox works normally.

Even in Safe Mode, Firefox cannot start its GPU and socket subprocesses. Steps to Reproduce 1. Download the latest Firefox from the official Mozilla website. 2. Install it normally in /Applications. 3. Launch Firefox by double-click or from terminal. Firefox starts very slowly and then crashes or becomes unstable.

When launching Firefox in Safe Mode: /Applications/Firefox.app/Contents/MacOS/firefox --safe-mode [Parent 1846, IPC I/O Parent] WARNING: Failed to launch gpu subprocess @MachCheckInListener TimedOut (Error:0) [Parent 1846, IPC I/O Parent] WARNING: Failed to launch socket subprocess @MachCheckInListener TimedOut (Error:0) [GFX1-]: Fallback remains SW-WR [GFX1-]: Failed to launch GPU process after 3 attempts

• Reinstalling Firefox does not fix the issue. • Safe Mode does not fix the issue. • The problem appears to be related to Firefox child process initialization (GPU and socket processes). • The browser often starts in crash recovery state. • Automation tests fail with: “Browsing context has been discarded”

Firefox is currently unusable on this machine due to repeated crashes and inability to initialize required subprocesses. • Any recommended workaround or diagnostic steps.

I have an iMac M4 running Tahoe 26.2, which has an admin account and three user accounts. Last time I tried to open Firefox in one of the user accounts, it asked for an admin password to install a helper, presumably to update. Rather than responding, I switched to the admin account and updated Firefox manually, (from the "about" option). If I now try to open Firefox back on the user account, I still get that request, but even after I enter the admin credentials, Firefox won't open. It does however open on the admin account and the other two user accounts, not getting the "helper" window at all. I have reinstalled Firefox (twice), and removed the profile form the troublesome user account, but the problem recurs. Where is the problem and how do I fix it?

I tried starting Firefox in trouble-shoot mode, but nothing changed.

When I try starting Firefox from the Terminal with the -P option, I get the following message

miki@Mikeliss-iMac MacOS % ./firefox -P 2026-02-11 18:14:06.242 Firefox GPU Helper[94978:60675173] Failure on line 688 in function id scheduleApplicationNotification(LSNotificationCode, NSWorkspaceNotificationCenter *): noErr == _LSModifyNotification(notificationID, 1, &code, 0, NULL, NULL, NULL) 2026-02-11 18:14:06.281 Firefox GPU Helper[94978:60675275] Connection Invalid error for service com.apple.hiservices-xpcservice. 2026-02-11 18:14:06.281 Firefox GPU Helper[94978:60675173] Error received in message reply handler: Connection invalid UNSUPPORTED (log once): POSSIBLE ISSUE: unit 1 GLD_TEXTURE_INDEX_2D is unloadable and bound to sampler type (Float) - using zero texture because texture unloadable

The Russian language is not listed in the "To" part when I want to translate a page. Although it IS listed if the page is in Russian, so it suggests to translate from Russian to some other language. The language is installed in settings.

As per the topic title. I would like pages to always automatically translate from english to my chosen language. However, when I select the option in the context menu, then revisit the setting, the check box remains unchecked. This remains the case on multiple tested operating systems, Arch Linux and Linux Mint. Thank you in advance.

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.

I'm on Win10. This morning I see that MSLOP has updated my desktop PC overnight. FF was open before the update and attempted to restart but couldn't restore pages. I told it to start a new session and the PC blue screened. This has happened before so after the PC restarted I shut it down. It blue screened a few times while also trying to restart FF. I shut it down with the power button. FF will not start with troubleshooting (shift while double clicking on FF icon). It crashes and I get the crash window. Latest crash detail is below. What next? Any help is much appreciated.

UPDATE: I went to windows settings, apps, and clicked on uninstall for FF. Immediately a message box, "Would you like to refresh instead?" popped up. Sure, why not? It thought for a while and updated. I logged in again and I am back to a functioning 147.0.3. I logged into my bitwarden extension and ublock origin is still there. No clue what happened earlier.

New laptop. Installed Firefox. Set up 2 of the "new" type profiles. Typical extensions (Bitwarden, Bit.ly, Firefox Color). Not too long after, Firefox will no longer launch and the only remediation I've found is to do a clean uninstall/reinstall including deleting registry keys. I've now done this three times now. Environment information

• i7 Core Ultra/32GB RAM
• SentinelOne - Corporate Environment. Installs Firefox Extension. There are no signs in the S1 portal or client that it is blocking firefox.
• nVIDIA RTX PRO 500 Blackwell Video Card. Updated to current driver 582.16
• Threatlocker - Computer is new and has been in "Learning Mode" so it isn't an issue
• Tailscale runs on this machine, but it doesn't seem to make a difference if it is running.

Nothing in the %APPDATA% crash reports folder for firefox. Crash dumps for firefox are in %LOCALAPPDATA%/CrashDumps. One read by AppCrashView is attached. It is a 0xc0000005 Access violation in StackHash_2264.

This is a problem where renaming the firefox.exe to firefox1.exe will get it to run but it seems to lose track of profiles.

Firefox is my favorite browser and I'd like to resolve this, but I really can't afford spending much more time on it or continually clean reinstalling and rebuilding profies. I've seen other similar posts, but no clear resolution.

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?

Hi people,

I have used Firefox for years but after the latest Microsoft Update it no longer starts or runs. Another product, Libre Office, also failed at the same time and I have been unable to resolve that problem either.

I have uninstalled Firefox, downloaded a fresh copy from the Mozilla website and reinstalled it a couple of times but when I click the desktop shortcut nothing happens. I can right click the shortcut and select the "run as administrator" command and something like the Firefox browser opens but all my shortcuts are out of date on it and the browser will not access anything on the net.

I also use Mozilla Thunderbird as my email providor and that is still functioning normally.

Is this some monkey business from Microsoft, a fault in Firefox or a fault somewhere in the inner workings of my computer?

I can not open my firefox browser. I never had this problem before. When I click on the icon I have on my bottom of my computer it says I can not get on it says many different error messages being sent. I am not a computer whiz so what should I do? should I uninstall it and re-stall it? would I loose everything I have book marked. HELP
