I've been using Firefox for a while, and while there are many things I like about it, it has always been a resource hog. In the past I could get around this by just killing Firefox in Windows Resource Manager and restarting, but ever since getting a new computer an upgrading to Windows 11, it's gotten worse. Every couple of days my computer freezes for 10 or more minutes, I'm having to do a hard reboot ever few days, and I'm even bluescreening about twice a month. I'm pretty sure Firefox is the culprit because killing it will usually resolve the issue.

I'm wondering if there is some way to put Firefox in a sandbox so it does not consume nearly all available memory and other computer resources. It is by far the biggest consumer of resources on my system and I do not want to dedicate 4GB+ of memory to an app that is just showing a couple of web pages and playing YouTube videos.

a black box appears over the search box when mouse is moved over the tab. Tried in safe and troubleshoot mode. Box still appears only in white I did find an answer previously but reinstalled firefox and the fix was lost. Problem resolved.

Thanks all for looking.

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.

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.

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.

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.)

In settings I have turned media.video-wakelock. to FALSE etc and firefox still wakes the computer

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 :)

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.

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!

Hello I am having major problems with Firefox at the moment and have done for a while. I curently have four pages open but as you can see from the attached screen shot of my Task Manager, there are 14 Firefox processes. The usage is OTT on memory and everything else. Could you tell me why this is happening? Currently it is running in Troubleshooting mode but that is not doing anything to improve the problem. It has been known to shut my computer down, as it gets too hot. I run on Windows 10 and Bitdefender is my security. All help is gratefully received. Thanks Lisa

26200.6899 - Windows 11 pro OS version 144.0.2 (64-bit) - Firefox version

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

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?

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!

Hello. My tablet, has limited memory, due to its age. I am now finding that one of the main reasons why it is so slow is because whenever I open firefox, it opens multiple firefox processes which drain the memory and in some cases crashes the system. I have followed all the advice given to reduce these multiple processes, however nothing seems to work and at least 6-8 firefox processes open each time I open it. I have unchecked the recommended performance settings as well as hardware acceleration boxes. However, I cannot find where to set the content process limit to 1. Please tell me how to do this and if there anything else I can try to stop it opening multiple processes or I may be forced to ditch Firefox altogether for an alternate such as Bing, Chrome or DuckDuckGo. Many thanks. Charlie

Firefox stürzt seit einigen Wochen immer wieder ab.

Auch ist es sehr langsam, oder lädt die Seiten nicht.

Auch kann ich nichts schreiben, zwischendurch.

Es nervt!

Und ein neues Update gibt es nicht.

Wenn es so weiter läuft, muss ich einen anderen Browser nehmen, was ich gar nicht möchte, da ich Firefox, seit Anfang an benutze...
