I am running Firefox in Windows 7 on a PC. When I start up Firefox, in WINDOWS Task Manager there appear between 20 and 30 instances of firefox.exe of different sizes in the Processes Window. I can End Process on most of them without shutting down Firefox or any of the other instances of firefox.exe. However if I shut down one listed with about 200,000K of Memory (Private Working Set), then Firefox shuts down and all other instances of Firefox disappear. If I open an new tab in Firefox, more instances of firefox.exe appear.

I have never seen this behavior before. I tried uninstalling and reinstalling Firefox, but the same behavior occurred. Is this normal behavior, or should I be concerned?

I have enclosed screen shots from the Task Manager. I also have a Dump File of a couple of the firefox.exe instances, including the large one, if that would be helpful.

Thank you.

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!

So, i have a laptop, with integrated cpu graphics (Intel UHD) and discrete gpu (RTX 3060), first times when i set in Windows settings to use Firefox powerful gpu, it just won't, i tried restarting browser but i forgot that i have opened private tab, so i not restarted browser. So, on any pages like WebGL Aquarium, i have pretty low fps, in comparison to other browsers (like Microsoft Edge or Google Chrome). Then, after i see that tab, i closed it, and after restart i got my fps, but.. still lower than other browsers, on WebGL Aquarium with 30k fishes, Firefox max fps is around 35, but on Chrome is around 70 (two times faster). I found one page that shows gpu that uses for acceleration, and it shows pretty weird information in Firefox. https://kdashg.github.io/misc/webgl/low-power.html So, in Chrome it says like "Nvidia RTX 3060 Mobile GPU", and when i choose integrated gpu for this browser in windows, it says like "Intel UHD GPU", but, in Firefox, on first tries it said same, but when i got discrete gpu acceleration, it says that i have "Nvidia Geforce GTX 980". I was like, what? Where it did come from? This explains why I have a fps two times lower but who will explain to me why this gpu is here? I tried to change all acceleration settings in browser, but when i just disabled any acceleration, still shows GTX 980 what is more weird than if it just shows like nothing or Intel GPU, cause is disabled but still uses hardware acceleration, but no matters if i let Firefox use recommended performance settings or set to use acceleration when is available, it shows GTX 980. I think it's about a bug, or something? I can't say that's Windows problems, drivers, or any other thing, cause, other browsers don't act like this, and i just don't have GTX 980 in my laptop on side with RTX 3060 and Intel GPU, anyone even know that laptop like this exists? Screenshot don't wanna upload here so i decided to place it on imgur. https://imgur.com/pyMZQr0

Since updating to version 135.0.1 last night, all kinds of interactive maps have been loading like the pictured attached below. Even maps in pdf aren't properly loading, loading black pages. Everything works completely fine in all my other browsers.

Firefox has started crashing immediately upon launch. The browser window never even opens, and all I see is the Firefox crash reporter. This problem just started today. Everything was working fine previously.

I have tried opening Firefox in troubleshoot mode, but it still crashes. I've also done two clean reinstalls, deleting all Firefox files in between. This has not helped either.

I've attached a screenshot of the detailed crash report. In case it's relevant, I'm running Windows 11 on a Microsoft Surface laptop with Snapdragon X processor. I know the Snapdragon has had some software compatibility issues, but Firefox had worked fine on it until today. I'm totally stumped, and appreciate any ideas!

I walked away from my laptop for about an hour and when I came back my task bar was gone. What happened to it? and how do I get it back? Below is the spec's of my lap top that I use/have been using/task bar missing

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.

I have had this issue for a couple weeks now with youtube. When running in a private tab it will frequently not accept input for something like 10 seconds at a time. Playback works totally fine, no real stuttering or lag in the video, but pressing pause will generally take significant time to actually pause. This is true of all other inputs including keyboard commands, clicking on links, right click, etc. It seems to have a rolling window where inputs are accepted because if I wait for clicking play to work I can also quickly change the volume or right click a link. It'll even accept the input if I'm in a different window (like if I hit play then click over to my second monitor). This doesn't seem to happen in a normal window, only private. All other firefox tabs work totally fine with none of this lag, nor do I see any other issues on my computer. I haven't noticed any spikes in hardware usage nor am I using anywhere near all of my PC's resources.

I'm only running 2 extensions I think would interfere here (ublock origin and enhancer for youtube) and I've tried running with them disabled to no effect. All my extensions are up to date, as are my browser and OS, this has persisted through restarts (though it seems to take some time to come into effect after a restart). I've tried disabling hardware acceleration and clearing the cache.

So yeah, no idea what's wrong. It's not like unusable, just really annoying. Thanks to anyone that helps.

He said its down to some update which for some reason I dont have but in the attached image, he is able to add his own wallpaper in nightly but I am not for some reason. Would love some support
