Firefox Community Forum

We have an asp.net Blazor SPA (server side Blazor) that dynamically generates components within the page. Over time, there is a very large RAM leak under document-shared that climbs until the windows are closed.

We have tried various firefox configurations to try and either disable this shared storage as well as limit but with no luck. THe memory allocation is in GB of RAM space and cannot be limited or reduced until the window itself is closed/restarted.

Research online indicates this can happen due to colocated stylesheets and how firefox wants to cache styles aggressively. Adjustments to move stylesheets does not appear to help.

What configurations can I use to help prevent/reduce this high RAM usage? This does not occur in Chrome or Edge, I cannot replicate this well under FireFox for Windows.

When saving images from websites using the save image as feature, Firefox will freeze up and not register any mouse click or anything instead making a ding noise every time is register a mouse click. This will continue for like 30 seconds before it becomes normal then it will repeat this for every image. How can I solve this?

Firefox kept eating my RAM, running dozens of processes. I have gone into about:config and set the dom.ipc.processCount to 1 - then I restarted Firefox and found 5 processes running straightaway before even using the browser. I closed it down and have started it again and now there are 11 processes running with just one tab open. Firefox(9044) Utility(7552) JavaScript oracle Network (15912) Data Decoder (11364) GPU (18744) About pages (12536) Preloaded new tab Extensions (20544) Preallocated (16132) Preallocated (13780) Preallocated (16044)

The problem repeats on three different computers which are not infected with malware. One computer with slightly less RAM I now cant even use Firefox at all (though all other browsers work fine) because the tabs constantly crash due to the high number of processes. Is there any way to set the process limit low in a way that Firefox actually responds to?

Hey there since a week when I brows with Firefox on Windows desktop the RAM uses jumped from around 60% spiked to 92-95% RAM and that changed just come a long a week ago. If change brows like Chrome different story, back down at 65. So you can also see a massive number on Firefox system running.

Question: Whats the reason for the change? What happend?

Best, Janosch

Some websites won't load at all while other are very slow to load but some will load just fine, example Crunchyroll (screenshot attached) won't load at all its just spinning loading icon and a white page but if I try it in a different browser it works just fine, but with Youtube it will load but is choppy and low quality videos and same thing as before I load it in a different browser and no problems. I have tried every possible solution I can find from clearing cookies and cache to refreshing Firefox even scanned for malware and virus nothing has worked please help me figure out what is happening and why it's only with Firefox that I am having this problem and its not hardware can play online just fine and download games from steam perfectly fine.

So ever since the desktop browser got updated i have been experiencing critical crashes and lag where my pc screen freezes and then goes to black until i restart my graphics card and quit firefox in addition to tabs crashing and very weird performance issues overall, any fixes for this issue?

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?

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?

Hi, Once last week I had Firefox crash, like quite literally the window I had open just closed abruptly. Tried doing the refresh using the setup wizard and it did not help. Then I've tried uninstalling/reinstalling several times. Each time it'll open up like new, and within 10 minutes the window closes randomly and then Firefox doesn't launch anymore on my laptop. No error message, just does not launch whether I try to from taskbar or Home or even run as administrator. Seemingly random I've been using Firefox for months and it just started doing this last week.

Sorry for lack of other info, thanks for any help you're able to give.

After a few minutes of usage, firefox keeps freezing and crashing. Very frustrating. Seems to have started happening after recent OS upgrade.

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

On iGPU hardware, default dedicated VRAM is usually 0.5GB and the maximum is 2GB.

On my laptop Firefox only use 0.48GB(dedicated VRAM)/0.2GB(shared VRAM) when I set VRAM to auto(512MB) in BIOS.

The screenshot is when I set dedicated VRAM to 2GB in BIOS, and you can see the VRAM usage has increased to 1GB(dedicated)/0.5GB(shared).

It seems Firefox is restrict itself to dedicated VRAM and not fully utilize the vast amount of shared GPU memory. This makes sense on dGPU hardware but not on iGPU hardware. On iGPU hardware, the negligible amount of dedicated GPU memory exists only for compatibility to legacy programs, and Firefox should allocate all it's GPU memory from the shared GPU memory pool.

Dlaczego FIREFOX spowalnia i często karty się samoczynnie przeładowują? Nie zdążysz jednego artykułu przeczytać i się wszystko odświeża, cały czas się odświeża. Na konkurencyjnych przeglądarkach MICROSOFT EDGE i AVG SECURE BROWSTER cały czas działające odświeżanie nie występuje !!!!!

When I sign in, multiple firefox open, causing my machine to run slow. I have to go to task manager, close all the firefox and start over. I usually have to do this several times before I can get signed on. Once on, the new Windows 11 seems to work well with Firefox.

I noted in the multiple firefox accounts the following Group or User Names in the Details section. Are these normal or could they be the source of my problems???
