Looking at the Task Manager in Windows, Firefox is using 2700-3000 MB of Memory when running. I only have 13 tabs at the time of writing this but it is driving my memory up to 50%. (I have 32GB RAM). Is this normal? When I open the Firefox manager, the GPU seems to take like 1-2 GB and i think it is driving up the Memory. I also have UBlock Origin, Privacy Badger and a third extension called Copy Plain Text. This is just concerning me and would like to know if I'm overreacting.

before v151.0.2, didn't have a problem with firefox, now with this new release, it is really really slow, takes some time to start and load pages. what happened??

Wäre es nicht Sinn voller mal Firefox so zu Optimieren das er nicht gleich 50% des Arbeitsspeicher belegt. Ich beobachte schon länger das wenn Firefox eine weile Läuft sehr viel Ram braucht. Da gibts andere Browser wie Brave die viel weniger Ram belegen als Firefox.

Könnt ihr da nicht mal ansetzten und was Optimieren Bei den Ram Preisen Aktuell kauft man sich ja kein neuen RAM.

Immediately after restart and subsequently starting Firefox 153.0.3 my Windows 11, 16GB system shows that Firefox has started 11 processes, five of which account for most of the 1.2GB of RAM used. Why does Firefox run so many processes, and how can I make it use less RAM?

plz guys help me my eyes hurt so bad because of this

every time i open firefox for pc, a white flash appears very quickly

i tried every thing ai told me to, but still

i cant even record it it doesnt appear in video

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.

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?

День назад установил ваш браузер и он почему-то даже в простое просто грузит ЦП до 40-50% без причины раз в пару минут начинает резко грузить на какое-то время и спадает и так по кругу. В чем проблема? Стоит последняя версия соответственно

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.

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.

I open Firefox and Chrome with the exact same page:

https://en.wikipedia.org/

Chrome is using 296 MB while Firefox is using 590 MB.

What am I doing wrong?

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

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 !!!!!
