Mozilla Firefox 115.25.0 (x64 en-US) won’t close since my previous version was updated on 6/29/25. I have tried closing it in my Win7pro Task Manager on several occasions, and had even tried to uninstall and then reinstall it from my “Programs and Features” menu, but I keep getting a message that the program can’t be uninstalled until it is first closed. Nothing I do fixes this problem. HELP

Suddenly getting persistent "Gah. Your tab just crashed" error message this week; running Windows 11 on a Lenovo X1 Carbon 12th Gen laptop; I have run Firefox in Safe mode, disbled multi-process tabs, turned off h'ware acceleration, cleared cache and cookies, turned off BitDefender, Refresed firefox, updated firefox and windows, checked for malware, reinstalled Firefox, and attempted to create a new Firefox proficle (didn't run), all to no avail; attempted to use mozregression, but I don't have the skills. Would be glad of any help! Thanks

hello! Firefox began timing out and needed to be force quit starting yesterday; I didn't think anything of it until I reopened and Firefox continued to be unusable. It's not frozen or unresponsive, but it won't load pages or complete actions. I can interact with the browser and settings, etc, access about:crashes, but I can't actually submit crash reports; it just loads endlessly. When I close the program, it won't complete that action either; the app remains running in the background until I force quit.

Things I've tried:

Restarting the computer Uninstalling and reinstalling Firefox Clearing the cache

Other browsers work fine, as does the rest of my machine and internet. I'm submitting this using Safari because I can't navigate here using Firefox, but would really prefer to get back to my browser of choice.

Attached are the IDs of a few of the crashes I've had; they remain unsubmitted, sorry, because (as outlined above) I'm not able to complete the action when submitting them.

Since recently 1~2 version, my Firefox keeps consume large amount of memory and release it repeatedly

Even I restart Firefox and do nothing, it will start doing this again

I use about:processes and about:memory to capture this seems the main process's "tab.query" causing this, please check

PS: sometime it will consume till system max (64GB) and cause my OS out of memory. PS2: that wave-like memory usage is cause by Firefox

As of July 1st I'm unable to open www.funnyjunk.com on firefox I can do it through chrome or a 3rd browser on my phone and a friend who uses firefox can do it too. I have DNS over HTTPs settings disabled, troubleshoot mode and private window didn't change anything. Afaik I haven't installed anything new between my last successful and first unsuccessful attempt.

I've use Firefox or Foxfire for several years at the time I installed it I was using Windows 10. I now have Windows 11. Ever time I try to access he internet a window comes up and ask me to create an email address with Gemini. Google or Microsoft will not let me access my internet, [email removed]@nquinnlaw.com. How do I use Mozilla to access my email.

Recently I'm having an issue with Firefox that makes it so when I try to open it, it simply refuses to do so. Say on my desktop I double click the icon it will open for a split second and then instantly close and refuse to do anything afterwards. This is very frustrating, and I haven't yet discovered a solution and would really like to be able to use Firefox again. What is really strange is that this is a persistent problem not only on my laptop but at my pc as well which are two separate devices. If anybody can help or has experience with this problem to offer incite it would deeply be appreciated.

Suddenly they broke after the 140.0 update, but as it turns out, this is the case everywhere. Does anyone know what the problem is?

Verified on: Firefox Desktop, Chromium Desktop, Firefox Mobile Font: Calibri (No changes), Roboto (No changes) I've scoured half the internet, as if I were the only one with this problem...

I shop on several websites, and the customer review section does not appear on the product pages. Thinking extensions may be to blame, I tried opening those particular websites in a new private window. But I still was unable to see the reviews. It works fine on Edge. Is there any way to fix this?

I have a few passkeys saved in Proton Pass password manager. I can use them with any browser on any OS using various official browser extensions or applications. For Firefox, I use the proton pass extension (https://addons.mozilla.org/en-US/firefox/addon/proton-pass/).

The passkey for my Nintendo account doesn't work with Firefox. I tried with Firefox 140 on a Windows 10, on MacOS 15 (Sequoia) and on Linux (Ubuntu 22.04). Same problem each time: error message "couldn't complete passkey sign-in" (see the attached screenshot).

If I use the same passkey stored in Proton Pass with another browser, it works. I can log into my Nintendo account. I tried with Microsoft Edge on Windows 10 and on MacOS, and with Safari on an iPad.

It seems the issue is also related to the Nintendo website. I can log without problem into my Sony account (https://store.sony.com) using Firefox 140 and a passkey stored in Proton Pass.

Hi everyone, I use Firefox as the main browser for my iMac (Sequoia 15.4.1). Recently, Firefox has been incredibly slow. I'm able to boot up and open Firefox (140), but when I search for something or create a new window, it never loads. Is there a way to fix this? I can open the same websites on Safari, but Firefox is my employer's preferred browser. Additionally, my bookmarks are all saved on Firefox. Thanks for insights/ideas/solutions.
