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?

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.

I opened a new Firefox session (closed the previous one properly using the “Exit” option, without force-killing it) and had only 4 tabs open:

One YouTube video at 1080p One bookmaker site that may have a 240p video playing Two Flashscore tabs (static pages, no video)

When I end all firefox.exe processes, the Task Manager shows that about 10 GB of RAM is freed.

How can just four tabs be using that much memory? Please help me with this issue.

Thank you!

I AM SENDING TWO SCREENSHOTS IN ORDER FOR YOU TO SEE WHY I AM SAYING GOOD BYE TO FIREFOX OVER 4000 OF RESOURCES AS YOU CAN SEE AND FIREFOX HAD 4 TABS OPEN ALL OF THEN JUST OPENED UP SO THEY WERE NOT YET CONNECTED TO ANY WEBPAGE.

I CANNOT SPEND HOURS TRYING TO FIX THIS

SO I AM MOVING TO ANOTHER BROWSER

I JUST WANTED TO SAY CIAO

What minimum memory spec is recommended for current Firefox usage? Have new computer with 16GB memory, 512 storage, intel core Ultra 5-225 processor & windows 11. Have not set it up yet.

Will this fricking "The bookmarks and history system will not be functional" B.S. ever be fixed? Firefox didn't have this issue for years now for almost a year every time Firefox starts up on a cold boot I get this idiotic non-sense message!. I have to close the browser I JUST OPENED and reopen in. This error is pure B.S. as again cold boot, just launched there is NOTHING other than Firefox that might be accessing the various sql.db's...so if this message is to be believed Firefox is blocking Firefox from Firefox... FIX THIS!

My computer, being 7 years old (and without the space to upgrade to WIN11), has always been a bit slow with low RAM and storage. The swap from Chrome to Firefox essentially gave it a second life, as Firefox didn't need a lot of space to run. Recently, though, it locks up with almost every search, refusing to let me x out a tab and try to save myself for 3 minutes or more, and the bluescreens have come back, too. If chrome hasn't also gotten worse, I'm considering switching back. Does anyone know what happened? I haven't installed anything new.

It's really frustrating and disappointing, because I thought I had a solution when I swapped to Firefox.

I am running Firefox on Windows 10 64-bit, and I have lots of windows and tabs open. Occasionally I will get a message from Windows that I am running low on disk space. Recently I got the message, and I saw on my C-drive" "336,044,032 bytes free". After I did an Exit in Firefox, I saw "10,082,402,304 bytes free". The space that was freed was in the pagefile.sys file. Is this normal?

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.

Hello everyone,

I have checked a lot of other questions already but I can't seem to find a solution to my problem.

I have Firefox installed on an old Laptop with macos Catalina. Reinstalled it many times with and without extensions, without any data but it doesn't matter what I do, even on a blank slate of a new reinstall of Firefox it just takes way too long to load or doesn't load at all and then even hangs up so that I always have to force quit it and slows down the entire laptop. It also sometimes loads tabs only if I reopen them or have to go to an already open tap that has been working to be able to open it.

I have been feeling super frustrated for days because I can not figure it out.

Thank you all for taking the time!

Do Mozilla really have no idea why their browser is considered a better alternative to other browsers? Why do they insist on making their browser WORSE for the sake of jumping on the latest stupid tech trend!? Some new tech that makes everything it's used in perform considerably worse? Oh boy sounds like the perfect thing for firefox! If this keeps up I'm looking into a browser that's at least more open about the fact it doesn't care.

Hi, Please help with my issue: There are 2 Firefox browsers running on my Windows 10 desktop. How can I find one to delete it. My CPU is running very high in Task Manager. Thanks, I just can't find it and I desperately need to do so before my computer crashes! Many thanks any help you can offer is very much appreciated :)

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.)

FoxFire (v146.0) crash report is available. Here is infor on machine:

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.

Dear Community,

Using Cloud applications via browser and my mail webbased I have Firefox installed. This browser was in my opinion always the better choice, but last months I experience strange behavior, cache issues, freezing pages, crashing tabs which is very annoying and frustrating when working in the cloud. In the same session it is possible that I suddenly can't open objects anymore or click on URL's, buttons not reacting or even can't login again, even when I just was logged in successfully. After refreshing and restarting the browser or sometimes even after restarting my device, everything is working properly again for a while. The same issues I have when using the incognito browser, especially when I use this for cloud application for example. I can't explain and my questions are: - anyone experiencing, familiar with and or know of this same kind of browser behavior and - if yes, how to solve this?

Thanks in advance and kind regards,

Aad

When Firefox ver. 143.0.4 (64bit) is opened, I see many tiny groups of black dots withing the whole of the desktop display of this Firefox. From these black dots I see coloured lines traveling across the desktop within the Firefox desktop display. As I move the mouse these coloured lined move, disappear, and move around. Can you offer any suggestions. I am using Ubuntu UALinux Gamepack 22.04, The version of Firefox is an upgrade provided by Firefox updates. I have tried to uninstall this version of Firefox, same effect occuring. I have manually deleted every referance to Firefox, as this worked in UALinux Gamepack 20.04. I have used sudo apt update, sudo apt upgrade, sudo apt --fix-broken install, and sudo dpkg --configure -a. None of these can fix this problem. I restarted my Firefox today with the same problem, and found in the Help dropdown menu, and found troubleshoot mode. When I opened in troubleshoot mode, all these problems are not there any more.

Can you offer any help ??????

P.S. I tryed to take a screenshot of this problem, but the screenshot doesn't show this problem ?
