Firefox Community Forum

This happened once before - then cleared after the next update. Now, after a recent update, the browser display is unstable again. Not a problem with any other browser - so it's NOT the computer. Any suggestions ?

Thanx, Dennis

I am using YouTube. One singular tab of YouTube takes up 4 GB of ram. Two tabs take 8 GB. Having more than two tabs quite literally provides me 20 GB of memory usage. This is preposterous.

The fixes I have tried is

- Disabling all extensions; this does not help in the slightest. - Refreshing the startup cache - helped first 10 minutes went from 400mb to later 5 gb (one tab) - Refreshing the Firefox cache - helped also first 10 min, and then memory leakage came back. - Disabled YouTube Ambience - did not help.

I have a top-end gaming computer, this should not be an issue.

I am not sure what to do from here on out, please advice

ive just downloaded firefox and its giving me performance issues I play gta 5 all day with my chrome tabs open maybe more then 5 sometimes more then 8 and When I had more then 4 or 5 tabs my gta 5 started to lag when i opened my task manager i see that Firefox is using more then my Game.

After Firefox & Thunderbird update & Windows (11) update, it takes ages for the email programs to open and the web pages to open. Tried everything, to no avail. Any ideas apart from uninstalling and starting again? The imap lookup takes ages and when opening website pages it takes ages. Googles is very quick to open.

Since Firefox 157, each version is stealing more and more RAM. Why? My Windows XI, on HP with an AMD processor, are constantly losing more and RAM to Firefox. Is there any advice? Or must I suspend all updates?

Hi everyone!

I enjoy using Firefox, but I've noticed that browsers can consume a significant amount of memory when multiple tabs are open simultaneously.

I'd like to know if there are any built-in Firefox features or recommended settings that can help reduce memory usage while maintaining good browsing performance.

Are there any specific settings, troubleshooting steps, or features you recommend for managing memory usage without having to close important tabs?

I'd appreciate hearing about your experiences and any practical suggestions. Thanks in advance!

What causes Firefox to do a refresh. I stepped away from my PC for 15 minutes and found FIrefox doing a refresh when I returned. Lost all of settings. Putting the icons on tool bar where you want them is one of the frustrating things I have done in a long time and now, I get to make all my settings changes over again plus try to get the tool bar icons where I want them.

Firefox runs real slow when I changed screens. Sometimes many seconds, things just quit working screen goes blank.

Sometimes it goes to wrong screen. I do not know how to reinstall or update. I would like to talk to a person I am old. I have no technical ability at all. I am confused by all instructions online. Please help me

I AM RUNNING WINDOWS 10 ON THIS COMPUTER AND I FIND YOUR UP DATES EITHER STOP FIREFOX FROM WORKING OR LOADING PAGES AND I AM TIRED OF THIS...

FIX YOUR BROWSER SO I CAN USE IT OF I WILL FIND ONE THAT WORKS. I AM SITTING HERE WATCHING WHAT USED TO BE AOL'S OLD LOGO MOTION...

''''PLEASE FIX IT OR LET ME KNOW OF A BROWSER THAT WORKS OR I WILL FIND IT MYSELF''''.

Firefox was running very slowly on my computer. Web pages take a long time to load and sometimes Firefox becomes unresponsive. I have restarted Firefox, but the problem is still happening. Please help me fix this issue.

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??
