Firefox 146.0.1 crashes every time upon launch (basically fails to launch), even in troubleshooting mode, with exception code 0xc0000005. Prior to today, it was working fine. Windows does not show any updates made over the last couple of days. I am on Windows 11 25H2, and I'm current with updates. Chrome works. Edge works. I logged on to the same computer as a different user (different profile folder in the user AppData folder) and Firefox still does not work. I tried to refresh Firefox and that did not resolve the issue. I tried to uninstall and reinstall Firefox and that did not resolve the issue. I tried to run DISM and SCANNOW and that did not resolve the issue. No issues are detected with a virus scan. I am stumped - please help!

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.

As of 12/9/25, Firefox seems to now prevent Theme add-ons from working if there is a contrast setting configured in Windows configuration. (Version 146.0) Previously, this allowed a very aesthetically pleasing view. I would greatly enjoy having that option again. Thank you.

Hello,

I'm writing because I’ve encountered an issue with the tab groups feature in Firefox.

Some time ago, after a browser update, I noticed a new feature that allowed me to group tabs thematically — I could name each group (e.g., "Study", "Work"), choose a color for it, and save and close groups to reopen them later. I found it very useful and used it a lot.

Last night, I decided to declutter my browser and closed several tab groups using the built-in menu. A bit later, I shut down my computer, but perhaps too quickly. This morning, when I turned my computer back on, Firefox was very slow to start. After a restart, everything seemed to work fine again, and the open tabs were restored.

However, all my previously saved (but temporarily closed) tab groups disappeared. In the tab group menu, I can now only see the ones currently open. I’ve searched through all the settings and history but cannot find any way to restore the missing groups.

Is there any way to recover the tab groups that I had previously saved and closed?

Thank you very much in advance!

AI "summaries" or "explanations" have been popping up in front of actual useful text that I want to read. How do I disable this AI summarizer or turn it off? If this removes an AI chatbot, even better.

I recently added ChatGPT as a search engine option. I tried to use the voice interface to simply ask the question instead of typing it out. An error message quickly appeared that stated "To use voice mode, you'll need to enable your microphone and try again." I could not find a way to grant this permission. The only setting mentioning "permissions" was in privacy & security. When I click on "settings" I receive the following message showing websites which have asked for permission so that I could choose to grant it or not, but, what it does not provide is a way for me to grant spontaneously if I choose to. ChatGPT has not requested permission so how do I, without a request from a site, choose to grant them permission to access and use the mic on the laptop so that I can simply talk to it?

Hi,

Is there a way to save the settings in the widget (see image)? It's very annoying that you have to constantly select it again, especially if you are on a long script. I put it on: Translate from Italian to English, and then it does remember for maybe one or two times, and then it falls back to English to Dutch. The tool itself is useful, but very annoying that it doesn't remember the settings. If it is somehow possible, please let me know how, cause I can't find it anywhere, or I just don't know how to do it. If it isn't possible, maybe it's an idea to add it to the widget?

Thanks in advance for the help or a reply.

Kind regards, Giaco

Windows 11 on laptop

I've used Firefox for 20 years through the various iterations of Windows, and have been using it trouble free on Windows 11 since November 2024. Two days ago, however, When I tried to open the Guardian site (www.theguardian.com) it would open very slowly and not load and of the pictures. This gradually got worse, the site taking for ever to open at all, and always with the little dot in the tab at the top left going from side to side showing it was still loading. I have tried everything I can think of. Opened in troubleshoot mode, changed DNS settings, uninstalled and reinstalled Firefox twice (one time to see if it would work normally if I didn't actually sign in to my account). All to no avail. In fact now things are worse, in that the GOV.Uk website is now giving me similar problems - and a few other sites have become slightly slow and reluctant to open as well. My internet connection seems fine, and all these sites open without any trouble on Microsoft Edge. I am NOT very good at tech, and I am now tearing my heair out as to what I can try next.

Any help wopuld be gratefully received!

I tried logging into my account on a website. I decided to click on the passkey option to log in. Firefox had ask to access my passkeys and I mistakenly declined. But the pop-up doesn't happen again. It goes straight to "authentication failed" without trying to ask me again to access the passkeys. I don't see any setting for this in the settings page.

How do I change the permission to let Firefox access my passkeys? Or how do I make Firefox and Windows ask for my permission again?u I'd like to not have to reinstall Firefox if I could.

Why can't anyone fix this issue? Every day I have to go to about:config, enter "mica" then change from false to true or true to false to get these buttons to show up. It's ridiculous. I am currently using Firefox version 146.1 on Windows 11. Also, please note if I change the windows widget to true these buttons show up and are usable. The next days I have to change the windows widget to false and they show up and are usable so they work whether or not the widget is set to true or false. The problem is having to change the setting DAILY. I should not be having to do this.
