Firefox Support Forum

I just installed firefox on a brand new Windows 11 PC and Firefox continually crashes. I did a clean install and still I can't go a couple of minutes without a tab crashing.

Here are a bunch of the most recent: 44ff3780-ddbd-4fa7-88a3-a606a364988b 3b24eea5-9a72-46dd-a635-273a20269eb3 056a49bf-0388-4b16-ab5e-9e023ebfb3d8 08b199d3-9631-4cfe-9b3b-44a8869c3949 02cf78b7-9c94-4905-9c0e-49e38998453f 66220c6a-3466-4fed-b394-f8d00a0cdee5 26c2bfba-1f66-4257-b4a5-76ac54a7dc65 532a5cda-40b2-4dff-aae9-2bb387e5d64f 32670407-0436-47f1-9728-ac9730a3b320

I realise that Firefox uses up a lot of Memory (particularly as it tries to run each Tab separately). However, my Firefox seems to keep increasing its usage!

I can start with a number of Tabs open & (after refreshing each Tab - to ensure it is "lice" & "active") I will get (according to Windows Task Manager) about 1,300MB in use.

Without opening up any more Tabs & without trying to run any Web-Based Videos, over a period of a few hours it will increase & increase & increase - perhaps getting up to 4,000MB!

I've cross checked with "about:performance" (to open FF's own Task Manager), to show the individual Tab usage, & that NEVER totals up to anywhere near the figures shown by the Windows Task Manager!!

Obviously, my FF is fully up to date!

Any comments!

After this last update Firefox is really slow loading pages and has crashed on me multiple times, I have also noticed if the browser is up it slows other programs down now like when im burning a cd. Is anyone else experiencing this? Thank you

I am getting frequent crashs and many a times my pages will become unreadable, again automatically text changes to normal format after sometime. I am attaching screenshots.

Please also help me that why firefox tabs suddenly crashes. I am facing this issue only in mozilla firefox, all other browsers like chrome, IE and softwares are working smoothly.

On a daily basis I am getting a popup that asks me to force quit applications since the system has run out of memory. In the list of apps, Firefox Nightly is always using 100GB+ of memory. I restart Firefox and then get the same message the next day.

I had a problem a while ago with crashing, which i was able to get fixed thanks to this but now i have a new problem. It seems that firefox is having memory problems of some kind, for example, i can't even get stream raiders to load.

Wow... I just updated and am trying to use Firefox as my default browser yet again, however, yet again, it's RAM usage is ruining an otherwise good relationship. Why does this browser guzzle RAM so hungrily? I had to reboot it as I couldn't type any longer, without waiting every few letters before seeing them on the screen, and I've got 60 Gigs of RAM. But Firefox was using 22 of them!

This has obviously been an ongoing issue for years, both from my experience, and the 2,000 threads that come up in response to this issue. Come on guys, it can't be this impossible to create a functional browser that is more RAM efficient, what's the problem?

Oh, and it sure would be nice, given 2,000 results from my search, to be able to filter them by date. I'm using version 84, so threads dealing with version 50 or so, aren't going to be of much help...

Firefox suddenly started using more memory overtime like than i doubled check both in chrome and firefox like in chrome it is staying at a certain amount of memory for whole day and in fire fox it just starting to use more memory like i started using firefox because chrome is using high memory and now firefox suddenly started and it is not even staying at a certain amount of memeroy in ram so yeah i think its a glicth in new firefox update and if u fixed that than i can come on firefox again but now i am using chrome.

I had 9 Firefox applications running in my Task Manager which was taking up too much memory (over 50%)

I came across this topic and solution here and reduced the processes in the settings from 8 to 5.

Instead of reducing the number of processes - as stated in your reply - they have increased to 11 with only 2 tabs open.

Any idea what is going on here, and how can I REDUCE the number of Firefox processes?

when I open 2 firefoxs more memory is used. When I close one firefox my memory usage stays the some. When I open a new firefox my memory goes up until I am using over a gig. All other network software decreases memory usage, like Google Chrome, why can't yours?

Hi, since the last update, Firefox is taking a huge amount of memory and slowing everything else on my PC right down. Right now this support tab is the only webpage I have open, yet you can see in the screenshot there are 31 Firefox processes running, and over 1G of memory being taken. I've followed all the help threads and taken the steps in them - it's made no difference. Please can you help me find a way to tame Firefox. Also - I'm really not an IT expert at all so please can you tell me in very simple language :)
