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

Each time I click on Firefox from the Windows 11 Task Bar, multiple versions of Firefox appear in the task manager (see photo). Some have an icon next to them that says "efficiency mode".

The attached screenshot is what I got from loading Firefox to ask this question. Multiple scans of my computer using Norton 360 -- including the Startup Scan -- have found nothing awry.

The operating system is Windows 11 Pro Edition Version 24H2 (OS Build 26,100.6584.) Firefox says it is fully up to date.

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 !!!!!

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.

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?

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?

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???

ALL APPLICATION PACKAGES ALL RESTRICTED APPLICATION PACKAGES ACCOUNT UNKOWN (S-1-15-3-1024-1238444810-1356253261-2257478630-1143196962-1563090664-2414759320-12821011916-4218287853) Following these were the regular System Admin groups I am used to seeing.

How to correct if a problem.

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

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?
