Firefox Community Forum

For the past few weeks, my PC reliably crashed after a few chess games on chess.com with Firefox. GPU and Memory benchmarks are running through without issues, it did crash when starting a Steam game once before, but I wasn't able to find out why. At this point, I'm really curious to learn about what could possibly cause this, but don't really know where to look for it. Really wondering what special thing is happening after a game there that doesn't happen with other websites/browsers. Would really appreciate your help!

Running Wayland on Archlinux 6.15.7 with AM5 CPU and DDR5 memory. Sometimes wondering if it's a graphics issue since my display is connected via the iGPU, but I also have an NVIDIA graphics card installed that I use for games sometimes.

Hello. My tablet, has limited memory, due to its age. I am now finding that one of the main reasons why it is so slow is because whenever I open firefox, it opens multiple firefox processes which drain the memory and in some cases crashes the system. I have followed all the advice given to reduce these multiple processes, however nothing seems to work and at least 6-8 firefox processes open each time I open it. I have unchecked the recommended performance settings as well as hardware acceleration boxes. However, I cannot find where to set the content process limit to 1. Please tell me how to do this and if there anything else I can try to stop it opening multiple processes or I may be forced to ditch Firefox altogether for an alternate such as Bing, Chrome or DuckDuckGo. Many thanks. Charlie

Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

I've rebooted, reinstalled, can't get it working.

Dear Mozilla.

Yes, I'm using the dreaded Windows 10, I do understand it's at end-of-use, however this prob's been happening for ages. It's just got a little worse lately! (I've also got another hard drive with Windows 7 on it I swap the Windows 10 drive for sometimes. And we don't talk about the Windows XP hard drive with my music software on it. AARRRGGGHHH!!!! But the everyday drive with this problem is definitely Windows )

I don't use masses of extensions, just a VPN (which is there but not used a lot!) and is Proxy VeePN (that's its name, blame the designers, not me!) When I'm NOT using Firefox for a few moments, I hear the fans speed up, the hard drive spins like it's about to take off (old computer here!) The moment I touch the mouse, the fans all slump back to normal and the red 'HIGH USAGE' mark against Firefox vanishes back down to 'LOW'. Which makes it annoyingly difficult to analyze what's happening cos the moment I touch the mouse to find out what's happening, it stops happening!

Despite the above and its memory addiction - left to itself it munches memory like me with a crate of chocolate bars! - I do love Firefox best of all the browsers. I kinda know what causes the memory problem, by the way. I don't know all the techie terms but here's what's going on. Imagine you've got a house with an untidy kid in it. Every time one room gets too messy to use, you move into the next room. Eventually you run out of rooms. Then you restart the house back from day one, all the rooms are tidy again and you can use them all individually and happily - until Untidy Kid turns back up!

I'm on Firefox 148.0.2. If you've got any ideas about the CPU usage, I'm [email removed]@hotmail.com. It doesn't seem to matter what websites I've got in the browser, it just does this when I've got it parked in the background, it's like it's twiddling virtual thumbs through boredom cos it's not being used.

Yours respectfully,

Chris.

When I open Firefox it opens a maximized window with tabs, then it opens a minimized with a single tab, then it reopens a maximized window with all session tabs. Each window displays in succession, one window at a time.

I'm on desktop using Windows 11.

I just read a post saying this behavior was caused by the resist fingerprinting feature. Can someone explain how that causes the repeated opening of browser window 3 times. Is there a way to retain the anti-fingerprinting behavior w/o the multiple window opening behavior?

The image I uploaded is all I am getting. I even got on line one on one with my McAfee and they got on my computer. I need help guys. Is not just browse, I am also having issues accessing the website I know my account has been compromise. All I did different is add 2 adds on that were recommended by Mozilla and I removed them but it looks like the damage was already done.

When using firefox, and only when using firefox, I experience quite a lot of lag when using "google docs" (https://docs.google.com) and only when using "google docs", eg. this does not apply to, say, MS Word or google presentations.

Like I said this only applies to firefox, meaning google chrome and microsoft edge both work fine.

Here are some of the troubleshooting steps I've tried, without success:

  Launching in troubleshooting mode

  Disabling 0-RTT

  Disabling hardware acceleration

These issues do not appear on my machine at home, which also uses firefox, that however is a different version of Windows, an AMD cpu and a dedicated GPU instead of integrated, so idk if that narrows it down even one bit...

The computer on which the issues appear on is a HP Spectre x360 14, which if you don't want to search it up means I have 32gb of RAM @ ~7500MT/s, and an Intel Core Ultra 7 155H as my CPU.

I'd love to keep using firefox without having to fire up chrome every time i need to write/edit a document, which, as a student, is quite often...

Thanks a lot!

Hello everyone,

I have checked a lot of other questions already but I can't seem to find a solution to my problem.

I have Firefox installed on an old Laptop with macos Catalina. Reinstalled it many times with and without extensions, without any data but it doesn't matter what I do, even on a blank slate of a new reinstall of Firefox it just takes way too long to load or doesn't load at all and then even hangs up so that I always have to force quit it and slows down the entire laptop. It also sometimes loads tabs only if I reopen them or have to go to an already open tap that has been working to be able to open it.

I have been feeling super frustrated for days because I can not figure it out.

Thank you all for taking the time!
