It appears that I have a zombie Firefox browser running because when I close the browser using the top right 'X' button, the Firefox processes are still running when I check Task Manager.

If I end the Firefox task and reopen Firefox the first attempt seems to be stuck crashing because there's no crash log, but I can see in the task manager there's a crashhelper. A second attempt opens just fine, but the issue with that is my previously opened browsers are gone even with the setting to reopen them is enabled.

I've tried reinstalling, disabling my extensions, and updating Java, but none of these resolve the issue.

Support Firefox to be able to use different tab view modes on different windows! For example, two Firefox windows on different monitors, in my situation below:

- One on a 1920*1080 hori screen, with vertical tab sidebar disabled - One on a 1080*1920 vert screen, with vertical tab sidebar enabled for this window only in this case.

It brings much more convenience, at least for situations just like mine :)

Xfinity streaming works on Chrome and Safari but it stopped working on Firefox a few days ago. Why? I am using the latest Firefox version 140.0.4 (64 bit) and I can only receive my emails. The connection to the streaming service does not open. The Xfinity logo just sits there spinning and no connection. Please fix this. I much prefer Firefox to other browsers BUT....

Can’t login to EFTPS.gov using Firefox and Login.gov. I receive an SSL error message.

Greetings...

I have noticed in my Windows 10 Task Manager that Firefox has an excessive number of processes active when Firefox is started with only one empty tab. By excessive, I found eleven (11) Firefox processes today, and I have yet to even start using Firefox.

I have only a simple Theme enabled and no Extensions enabled in my Firefox. I have tried deselection of the "Use recommended performance settings" but this does not appear to help. Disablement of my Theme increased the number of Firefox processes.

Any idea how I can significantly reduce the number of Firefox processes that appear in my Task Manager when I use Firefox? I really prefer to use Firefox as my go-to web browser, but lately it has become troublesome at times.

Thank you in advance for your help with the above problem. Take care...

Recently, after the newest Windows 11 update, Twitch hasn't been loading correctly, the tab looks as if it finished loading, but the page gets stuck in endless loading, no other site has this problem, and it happens even opening links to Twitch channels directly. I've added and screenshot of the problem.

I'd love some help or at least know if this is a problem on Twitches end or not. Thanks.

I have 374 saved Passwords & User names in Firefox on my computer. Just bought a new PC and want to transfer the data to firefox or chrome on new unit. How can I do that? Is it possible to transfer the data?

thank you, Rena

I wanted to completely disable TLS 1.3 when using Firefox, so I set security.tls.version.max to 3 (which corresponds to TLS 1.2). That worked up until I got version 140.0.4 installed - now it completely ignores this setting no matter what I set. I tried using cloudflare-ech.com website for test and it confirms that my browser uses TLS 1.3 with ECH. I also tried modifying security.tls.version.fallback-limit to 0 and security.tls.version.min to 0 to get a possible range of TLS 1.0-1.2, but it still uses TLS 1.3.

hallo zusammen wo finde ich in firefox eine funktion, die mir die zuletzt angesehen und geöffneten tabs wieder herstellt?😐

in den einstellungen ist "Vorherige Fenster und tabs öffnen" angehakt.

es kommt aber wiederholt nach updates dazu, dass die letzten fenster und tabs nicht wieder geöffnet werden, sondern nur 1 tab mit der festgelegten startseite.🤷‍♂

muss ich mich damit abfinden, dass die letzten tabs hin und wieder im nirwana verschwinden? oder gibt es auch dafür einen tipp für laien?🙏

Hi Mozilla Community,

I run a food-focused website that showcases restaurant menus, and I’m currently having trouble with one specific page—https://olive-garden-menu-with-prices.us/—which loads significantly slower in Firefox compared to other browsers like Chrome or Edge.

The page is mainly text and optimized images, and I’ve minimized scripts as much as possible. Still, Firefox seems to hang while rendering or takes a long time to fully display content. Could this be due to any specific Firefox rendering behavior, caching issues, or something I may be overlooking?

Any tips on how to debug or optimize page performance specifically for Firefox would be really appreciated. Thank you!

So, as has been announced, FireFox 115 ESR will get updates until septempber 2025. This deadline has been extended multiple times. What factors are being taken in consideration when deciding whether to extend support again? With server 2008 updates you can get windows 7 up to date until 2026, sort of. Ending support in september would still be sad, because people too stubborn or not willing to upgrade probably still wont when support of firefox ends. I am a firefox on windows 7 user myself too, and it would be sad if they dropped support. Ill have to use a backported fork by the community

So thats my question, what factors matter in terms of extending 115 esr support again?
