I updated to Firefox 141.0 and now Google Maps is not working correctly. When I look for directions the map does not show the route. If I go to street view I get a black screen. Google maps is working fine on Edge or Google on the same pc.

After many attempt, I cannot complete to add-on of the IBM Security Rapport , this is important and need assistance. I cannot locate in the add-ons or extensions using Firefox. Thank You

In FF desktop, Settings > Privacy & Security > Enhanced Tracking Protection > Manage Exceptions, my list of exceptions are being cleared/deleted/wiped. Why? I have Facebook.net and Facebook.com saved as Exceptions and they keep being wiped/cleared/deleted. Could you tell me why?

Also cookies exceptions are cleared after an upgrade, not cool.

Thank You for you assistance and support.

I am on Linux Mint 21.2, and I just updated Firefox (141.0). Now, the bookmarks bar, toolbar, and the tabs (everything above the displayed page), as well as the menu, bookmarks menu, and sidebar, are in light mode even though I have dark mode set (They were dark before the update). I tried playing with the Dark Mode settings to no avail. My system is set to dark mode in general. Are others experiencing this? Is there some sort of fix?

Since updating to Firefox 141.0 (Win11), I've had issues with performance and on-screen behaviour of dynamic web pages/sites. The problems do not manifest on Chrome, or on a reinstalled version of Fx 140.0.4 on the same computer running at the same time (and with copy of original profile's data files, extensions etc.), they do manifest on a new Firefox 141.0 profile with only one tab open.

The problem happens on dynamic pages (e.g. gmail.com, boardgamearena.com/lobby) but doesn't seem to happen on static pages. Note that this doesn't depend on page elements moving around the visible window (e.g. panels opening and closing).

The manifesting problems:

• Screen pointer rapidly switching between standard arrow pointer, mouse with index finger (clickable link) and serifed-style insertion bar, even when positioned on a part of the page that is not a link or a text box. Video (MP4, <1MB) showing behaviour at https://imgur.com/a/absjTh4.
• Browser intermittently fails to respond to browser actions (mouse clicks, keyboard entry)
• Small increase in browser CPU usage

Problem is worse if general CPU usage (from other applications) is already high - low CPU usage reduces but doesn't eliminate the problem. (Established by changing my BOINC settings and/or snoozing BOINC and observing; I have a gadget that monitors CPU and other resource usage.)

The fact that I can see the problem occurring on Fx 141 but have Fx 140.0.4 working fine at the same time on the same page, suggests that this is a Fx 141 issue. Regular malware scanner and an alternate found no issues.

Happy to do more diagnostic testing if it's helpful.

Just noticed that Firefox only has translation for Chinese Simplified from Mainland China, but no Chinese Traditional from Hong Kong and Taiwan users. Any plans to get it going? I would hate to switch back to Chrome or Edge instead.

Tabs are not restoring after session closed. I have tried the profile suggestion. I verified my settings say open tabs from last session. Rebooted. Cleared cache then opened tabs then closed and it keeps only opening one tab. It crashed last night with tabs on it and this was the results once I brought it back up.

Hi everyone

I used Refresh Firefox option and it created "Old Firefox Data" folder on my desktop.

Awesome stuff. Sadly I cant get rid of it, here is why:

1. At first it said that the folder is used by another program and I cant delete it because of that. Cool, I decided to uninstall Firefox and make a clean install, so I have space to delete the folder too.

2. Long story short, it didnt work. I removed Firefox and tried to delete that folder, but wait for it, yeah I cant because I need permission from MYSELF. Awesome stuff.

3. I decided to use safe mode, so I used run command to run msconfig and I changed it to boot in to safe mode. But wait for it! YES! Its bugged and I cant login in safe mode, because pin is useless and it doesnt give me option to use password, so after hour of various things I got back to my normal mode via CMD commands. THANK YOU MICROSOFT.

4. So now Im stuck with the lovely "Old Firefox Data" folder, which cant be removed normally, neither in safe mode and wait for it! NEITHER WITH ADMIN CMD, not even the takeown /f "Old Firefox Data" /r command. THANK YOU MOZILLA!

So is there someone knowledgeable enough to help me to get rid of that folder pretty please? Like really a lot please.

Hello, I just used the Firefox 141.0 (aarch64) wizard for Raspberry Pi OS 1.0, to import bookmarks from Brave, however the wizard said 0 bookmarks imported.

I also manually exported and imported the bookmarks.html file and the latest bookmarks aren't appearing at the top. It seems the bookmarks are nested in some bookmarks directory by default. I'm confused?

Also I tried a manual import several months ago but same issue about some strange nesting structure rather than simply appearing at the top. Now I'm really confused and worried I'll lose my bookmarks as there's about 3 version in various nested structures. Please help just make an easy move to Firefox.

Just updated from version 140.0.4 to version 141.0 and all my bookmarks AND browsing history are gone! I do see the appropriate files in my Firefox profile folder.

I tried following the instructions in the "Fix "The bookmarks and history system will not be functional" error message" article (https://support.mozilla.org/en-US/kb/fix-bookmarks-and-history-will-not-be-functional?as=u&utm_source=inproduct&redirectslug=The+bookmarks+and+history+system+will+not+be+functional&redirectlocale=en-US), but they are not correct, i.e., Solution 3: Update Security Software definitions does not apply as I have Defender turned off in favor of using ZoneAlarm. And those instructions say to update the definition, but there's not place to update the definitions.

I tried to import bookmarks from the Bookmarks folder, but when I click on "Choose file", Firefox either does nothing or shuts down without displaying any error.

100% disappointed with this update!

Roughly every 2 weeks I backup important files to a external hard drive.

One of the things I always backup is my Firefox profile. I have been doing this for years without any problems.

I 7zip my profile and copy it to the hard drive.

I tried to do this yesterday (July 25 2025), and was getting access denied messages for files in the profile. So I tried to simply copy the profile. Same thing access denied.

I cleared the history, used wise disk cleaner, rebooted my machine and tried again. Same thing access denied when trying to backup or copy the profile.

I am assuming that this is happening since 141 because I updated Firefox since the last time I backed up my profile, and never had a problem previously.

Could anyone have an idea what the problem is? Thank you for your time.

All of a sudden, I can't access several websites through Firefox that I have used for years -- but I CAN access them in other browsers, like Chrome and Safari. Also, Firefox no longer works with my password manager. Until about two weeks ago, I could always autofill login information, but no more.

What gives? I am up to date on my IOS (Sequoia 15.5) and on my version of firefox -- and my password manager app. Superfrustrating. I hate to have to turn to Chrome as my primary browser since I hate Google, but I might end up doing that and just not using Firefox anymore, after like 20 years of having it as my primary browser.

Would it be possible to code in an F-key that would automatically send a URL to Chrome in the case where you attempt to view a page or video in Firefox and it hangs or just does nothing? Then with one key we could just be taken to Chrome where the page would work correctly! That would be just awesome! Firefox has really gone down the tubes as far as reliability is concerned. I only use it because I prefer the layout but when it fails (every day multiple times) Chrome is the solution and it always works. Why is this? Can't the FF folks write a decent package that works?
