Firefox Nightly (next generation web browser test) has no animation delay when playing sprunki, but there is a bug in the beta and current versions that become delay. (That's why I use other browsers.) There is no delay in other browsers. I hope it will be fixed.

I'm very frustrated with FF. It's running slow. Downloads are slow etc. I've tried everything that FF has recommended up to and including "refresh" with no effect. It's getting to the point I'm considering not using FF. Does anybody have any suggestions?

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.

Lately, I’ve noticed Firefox consuming more RAM, especially with multiple tabs open. Is this a common issue in recent updates? What are some tips to optimize Firefox performance on lower-end PCs? Would love to hear your experiences!

When I open FF 137 on my iMac running OS 12.7.6, it just keep trying and trying with no link. When I try and quit it needs to be forced quick to stop running. There are no fire walls and it worked yesterday 4-5-25 just fine, but no go today. I tried replacing FF and still no luck, what do I try now, [email removed]@yahoo.com

For the past few weeks Firefox has been crashing and freezing often. Crashes are worst when trying to access Protonmail, which almost always crashes the tab instantly. Freezes happen most often when browsing Reddit, and also when watching Youtube, but crashes and freezes can happen on almost any website.

I have tried changing profiles, refreshing and uninstalling/reinstalling, but the problem persists and seems to be getting worse over time.

Here are some recent crash reports:

Will be grateful if someone can help me get to the bottom of this Thanks

I restarted Firefox on my Mac earlier, which I think updated it from 136 to 137. After reopening it, web pages won’t load anymore. They either time out or just load indefinitely without doing anything. I went through the troubleshooting page and tried reinstalling it, which didn’t help. My computer’s firewall is off as well. I’ve tried refreshing it multiple times, and I get a message that Firefox has crashed before it actually refreshes. After that, pages will load normally for a very short amount of time (about 30 seconds) before stopping again. Pages are still loading normally on Chrome and Safari, so it’s only Firefox that’s having an issue. Does anyone have any solutions for what this could be/ways to fix it?

Firefox has recently started crashing multiple times per day. The crashes do not seem to be website specific.

Here is a list of my submitted crash reports. Please help.

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.

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.

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

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

Is this a bug or config problem?

Occasionally, FF (Linux desktop) starts using a lot of memory. I kill tabs (sometimes it is OK to kill YouTube or X, sometimes not)

Eventually it starts impacting the system using so much memory. I terminate the FF instance. Often. More often than not. There is a separate task still running and I get the "Firefox is still running" when I try to restart. I then kill the remaining FF task via the OS or the process monitor. Then FF restarts.

Is this an issue with addons (I am running very few - uBlock Orign, and Privacy Badger and Cookie AutoDelete. Are the only ones active most of the time) Or is it an actual bug with garbage collection, and tasks getting away? Or is it an OS issue?
