Hi!

I don't understand. Firefox is eating up memory again in the latest versions, and on top of that, it's the GPU on my PC.

4GB for the app and up to 8GB.

Are you mining Bitcoin on my machine?

What are you doing?

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.

Anyone else see this? When I click the mouse wheel to enable autoscrolling, before I get halfway down the page Firefox starts eating up processor time. You can hear the fan start spinning up until it is screaming at 90%

Mozilla Firefox for Linux Mint Mint-001 - 1.0 142.0 (64-bit)

Firefox 144.0 on a W11 PC with all updates.

Firefox is running multiple (10-13) windows with 5-10 tabs each. Even if all Firefox windows are minimised and not being used, memory usage goes up all the time. It is currently, according to Task Manager, using over 5 GB of 32 GB of available memory. CPU is sitting at ~4%. Individual tabs, like Youtube watching CNN suddenly freeze and are no langer accessible and can't be unfrozen by anything I have tried. Even the mouse pointer is not displayed inside this tab I need to restart the entire PC several times a day only to have Firefox usable. I have turned off efficiency mode, but this did not change anything. I'll include a system snapshot with msinfo

Any ideas?

Have been having an issue for the past month or two where if left in the background firefox will slowly start to eat up my available ram. I was using it like this perfectly fine for years previous to now.

I dont have this issue when I'm actively using it, only when I tab away from it and specifically its not on screen. Once I tab back to firefox the ram usage immediately dips back down to normal. I have tried many things to try and solve this like doing a clean install of firefox, getting rid of extensions, clearing my browser cache, closing all other apps to verify it was just firefox, clearing my history, turning on hardware acceleration. Nothing seems to help, im really at a loss and I don't understand what changed besides it being updated in the past couple of months.

My computer is fairly heavy duty and I have 16gb of ddr4 ram that again was working perfectly fine to run firefox before these past couple of months. As a result of this issue however if left in the background for too long on accident firefox uses up all my idle ram and starts causing other programs to not be able to run and has even crashed my computer previously when trying to run a program like clip studio paint.

I have noticed that while running the firefox task manager there is definitely some difference in memory usage when i tab back in after letting it be in the background so I have attached screenshots of the regular usage while tabbed in and the captured usage when i tab back in.

Any possible solution is welcome because I really enjoy using firefox and i dont want to have to switch browsers unless absolutely necessary.

On my main desktop computer whenever I try to open a Channel page on YouTube, Firefox will start to lag and either tell me it is slowing down Firefox and I need to stop the tab or just crash.

Sometimes after I refresh a random number of times, it will load the videos tab and then be fine on that channel. On other occasions it will never load the channel's Home page or Videos page and I have to close the tab because it won't load or change.

This only happens on my desktop computer. It it more likely to happen if the page has a home screen video.

Let me know what you think. Thanks

Of 3 macs in the house, all on OS12, the one on ethernet to the ISP has been failing regularly: 1.) fails to collect history 2.) fails to present long-time home page 3.) if it does boot-up properly, expected behavior slows down markedly during a session on the computer (Usually rebooting the entire machine restores this. This morning even that didn't work.)

A few days ago, something happened to the Firefox browser. The speed is simply terrible, sites are loaded for several minutes. Reinstalling does not help. Other browsers work fine.

the crash report ID is dd1e4f07-c2e0-4372-be7f-e82820250128 this is odd, Laptop was running linux mint, i beleive 20. mate. i reinstalled to the latest 22 and then copied over my .mozilla folder since then FF has been crashing. so i opened it in troubleshoot mode and it still crashed. so i moved .mozilla over and let FF recreate it and its still crashing.

im not sure where to go from here.

here is the crash report. https://crash-stats.mozilla.org/report/index/dd1e4f07-c2e0-4372-be7f-e82820250128

I have been experiencing issues of extreme CPU consumption.

When I look at Task Manager, I see tabs consuming resources - tabs I have closed.

See attached open tabs screen shot, and task manager screen shot. The Register (tech website) is clearly consuming CPU and memory, even though I closed that tab yesterday. WTF is going on?

Linux Mint 22.1 Cinnamon Cinnamon 6.8.0-90-generic

Firefox is installed from the package manager, not as a flatpack.

Extensions: Privacy Badger, and uBlock Origin are installed and active on most tabs. (YouTube has become temperamental about privacy extensions, and a few other Google-related sites as well) CookieAutoDelete - though that just deletes cookies/sites data some seconds after a tab is closed.

The Register example is just for reference. The service that seems to consume large quantities of CPU, even after I close all related tabs is YouTube. It has on occasion made the system crash.

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.

I have tried for several days to get Firefox to use this GPU; I cannot. Chrome, and Edge use this GPU without issues.

I am using Firefox 151.0 (64-bit) 20260516144017 on Windows 11 Pro 25H2, 26200.8457 Nvidia RTX 2000 Ada Generation Laptop GPU with latest driver: NVIDIA RTX Driver Release R595 U4 (596.36) Tue Apr 28, 2026.

Windows > System > Display > Graphics > Firefox GPU preference: High Performance (NVIDIA RTX 2000 Ada Generation Laptop GPU)

Firefox Settings: General > Performance:

unchecked Use recommended performance settings
 checked    Use hardware acceleration when available

My latest combination of settings are:

gfx.webrender.all = true gfx.webrender.force-disabled = false

webgl.default-low-power = false webgl.disable-wgl = false webgl.disabled = false webgl.enable-prototype-webgl2 = true webgl.force-enabled = true

I have tried several combination of settings to no avail.

I always get: about:support > Graphics > Compositing: WebRender (Software).

Any help is very appreciated -- thank you.

Hello Firefox Team

I'm having a problem with Firefox running very slowly, especially when watching YouTube videos. Videos take a long time to load, keep buffering, and sometimes get stuck while playing. The browser also feels slow overall, not just on YouTube. My internet connection seems to be working normally. I have already tried clearing all browsing history, cookies, and cache, but the issue still persists. I'm not sure if the problem is related to Firefox settings, extensions, hardware acceleration, or possibly a hardware issue with my PC.

I recently updated my Firefox browser from version 136. to version 137. and after the update I was unable to get online to any website I tried and Firefox would freeze and crash, generating a crash report that Mozilla probably didn't get because firefox couldn't send it. Safari was working, as was Chrome, so I know it wasn't a network issue. I cleared the cache and tried again and still nothing. I then uninstalled Firefox and reinstalled it from the Mozilla website, (had to use Safarii to get the Mozilla website) and still could not get to any websites. I'm on a Mac runnning OS 15.3.2 and I have a bootable backup of my machine that still had a copy of Firefox v 136 which i reinstalled on my mac and it works. What can I do to update to 137?

For about the last month, if I click on a link in an email or on a website that should connect to another website, there's a long delay in reaching that second site. This did not happen before. The delays are intolerable and do not occur on Chrome, for example. I prefer to use Firefox, but I feel I have no choice but to use Chrome instead. Can my issue with Firefox be fixed? Thank you for considering this issue.
