After updating Mozilla Firefox to the latest version, it changed the default language from English (US) to German (DE) although English (US) is currently selected as the default language. It will not change back to English (US)

Hello,

I've tried running "firefox -P". I've also tried deleting ~/.mozilla. No matter what I do, I still keep getting this message.

OS: Linux 6.10.13-3-MANJARO Firefox versions: firefox 131.0.3-1 installed from the Arch repo via pacman; also firefox-132.0.2 installed from tarball downloaded from firefox.com and unpacked as /opt/firefox.

With firefox 131.0.3-1, I get the following error message:

[Parent 33389, IPC I/O Parent] WARNING: process 33445 exited on signal 9: file /usr/src/debug/firefox/firefox-131.0.3/ipc/chromium/src/base/process_util_posix.cc:335

With firefox-132.0.2, no messages are printed.

What is even more confounding: I have 2 user accounts on this computer. When I login as myself, I get this popup. When I login as the other user, firefox opens up fine.

I've already looked at the following, but that has not helped. https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles https://support.mozilla.org/en-US/kb/how-run-firefox-when-profile-missing-inaccessible https://support.mozilla.org/en-US/questions/1327628 https://support.mozilla.org/en-US/questions/1396772 https://support.mozilla.org/en-US/questions/1454745

I'd be most grateful if someone could please suggest any other alternatives to try. Thanks!

A problem with an x.0 version? I've been using FF from "source code" for years on Debian Linux, but this is the first time such an update is failing after the most recent update to v133.0, as illustrated in attached image. How can I now update to the fix for this problem, please?

Hello. Why doesn't Fiery Fox release a portable version of the browser? What if everything was in one folder and didn’t shit throughout the entire system?

We kindly ask you to start releasing a portable version.

Thanks for your understanding.

Best wishes.

I'm having trouble installing Norton Password Manager, I keep getting a corrupt file, won't install, so I am running through the checklist of possible fixes.

The one I am up to is this :-

Refresh Firefox Click the menu button (≡). Select Help, then choose More troubleshooting information. Click the Refresh Firefox… button on the right side of the page. In the confirmation window that appears, click Refresh Firefox. Firefox will close and restart. When it finishes, a window will show the data that was imported. Click Finish. Choose whether to restore your previous windows and tabs, then click Let’s go!.

I cannot find the "Refresh"

I've run Troubleshoot Mode

I have cleared the startup cache, problem not fixed.

Currently on 131.0.3. Started having this issue around the time 131 dropped.

I press Ctrl-shift-O and bookmarks manager won't open. Bookmarks manager opens normally if I use the menu to open it. Keybind won't work in troubleshooting mode so I know it's not an addon, and the hotkey works fine on other computers with Sync enabled so I know it doesn't have to do with my synchronized settings. Also won't open with a fresh profile so I am very hesitant to reset all my settings.

I use this keybind multiple times per browsing session so it has had a major impact on my usage. Not sure what to do. Please help!

I'm going to try a graphics driver update in the hope that helps. This is on Windows btw.

I'm using Firefox Developer Edition 132.0b2 (64-bit) and noticed that the only way to open a new tab is to click on the pancake icon and select new tab. The "+" icon in the tab bar is missing.

I also noticed that there is no way to reload the page (especially doing a hard reload). This is a major issue when making updates to websites and wanting to see those edit. Clicking in the address bar and then on enter will reload the page, but does not do a hard reload, so the cached version of the page is displayed, not the updates.

Firefox updated to 113.0 and moved tabs to top, above the address bar and the bookmark toolbar is now on the bottom under the address bar ... Is there an updated CSS file I can copy that will restore bookmarks toolbar above the address bar and the tabs below the address bar? So the order would be: Menu Bar, Bookmarks Toolbar, Address Bar, then Tabs Bar? This really is hard to work with. Thanks!

i was using firefox with multiple tabs for most of today, had to shut pc down to run errands. When i restarted pc, firefox would not start, i have it pinned on my task bar/start menu/whatever. I opened my system moniter to see what was going on when i tried to start firefox and the processes do not show up in the process list. I tried a reinstall with the ubuntu software store and no noticeable change in behavior. Not sure how to get into the profile section, the option for it with a right click on the firefox icon does nothing seemingly. Under normal operations i have seen two firefox processes listed.

When l look at Settings>Updates>Check for updates: I am usually presented with an update such as the one just now: Security Intelligence Update for Microsoft Defender Antivirus - k32267602 (version 1.443.4.0) current channel (broad) completed00 -

After checking for updates I will then go to SETTINGS> IT clearly shows that I am running Windows 11 PRO.

CAN SOMEONE PLEASE TELL ME WHY IN PLACES THAT ARE TRACKING ME AND TAKING MY PERSONAL INFORMATI0N, THAT IT SH0WS OR SAYS THAT I am running Windows 10? I often see it if I sign into one of the many different accounts that require 2 factor authentication, which will send me a notification alerting me that someone has signed into my account from a NEW DEVICE. OR FROM AN UNKNOWN DEVICE. That is when they ask if I recognize this login and it shows device and location from which the login attempt is happening. IF I answered honestly, (because it is showing a login attempt happening from a (WINDOWS 10 SYSTEM) and my system shows Me that it is running Windows 11 PR0: it would flag as suspicious and my account would get locked up for sure. Instead, because of the odd hour of the night it occurs, that combined with the location I know it is myself and even though it says "ON A SYSTEM RUNNING WIND0WS 10", I force myself to lie and answer that I do recognize the attempt. PLEASE SOMEONE HELP FIND A SOLUTI0N TO THIS ERROR. THANK YOU IN ADVANCE

After upgrading Firefox, i cannot connect to internet. My internet is working fine, but none of the websites can connect. I restarted Firefox twice. I restarted my laptop (windows11), can you help me? Email removed for privacy

On the newest firefox update on Windows PC My PDF reading has been not displaying PDFs correctly on Firefox I tested on other PDF views and they work as normal (All images are normally white with black text PDFs) Sometimes it displays nothing at all (as seen in Image 1) Some pages will display correctly but the rest won't (as seen in Image 2) Some pages will display text but strangely (as seen in Image 3) It does flash white sometimes while scrolling but it still doesn't show text

idk when exactly this nonsense happen or with which update but thats outrageous.

why the hell it canceled in my setting the check mark at startup for opening previous tabs?! i haven't touched the settings in ages since i set them up so it had to be one of your stupid updates.

fortunatly chatgpt had a solution to bring all my tabs back otherwise i'd fucking rage out.

i'v been using firefox for ages but after this i was really thinking i should switch to something else.

Hello, could you please let me know if updating Firefox as suggested (version 128) will be compatible with my iMac OS X Version 10.9.5. Thank you very much. Kind regards AS.

I looked at the system requirements page at https://www.mozilla.org/en-US/firefox/141.0/system-requirements/ . For Windows devices, the operating systems supported are listed as "Windows 10 or later".

In October 2025, Microsoft officially stops providing feature and security updates for Windows 10. However, they offer consumers and businesses the option of enrolling in 1-year, 2-year, and 3-year subscriptions for Windows 10 devices which will provide another 1-year, 2-years, and 3-years of additional security updates. You can read more about this at https://learn.microsoft.com/en-us/windows/whats-new/extended-security-updates

For those individuals and businesses who will be enrolling devices into the Windows 10 ESU program, will Mozilla continue to support Firefox on Windows 10 after October 2025, at least for those receiving security updates through Microsoft subscriptions? Or at that point will Mozilla consider Windows 11 to be the only supported Windows operating system?

Thank you!

With the new version 132.0. I can no longer access an IP address in the home network. For example 10.0.0.100 It is always searching https://10.0.0100 With the old version 131.0.3 this was possible without any problems. Here is it 10.0.0.100http
