Whenever I restart Firefox, it uses about 30% of my RAM, however this increases over time and after a week it can be over 60%. No new extensions, tabs, windows opened, nothing changed from usage of day 1 to day 7. I have attempted everything in the support post for Firefox taking up too much RAM, and nothing has led to longterm solutions. This issue originally started about 2 months ago so it hasn't been consistent, but I haven't changed anything either in my browsing habits or the hardware of my computer to causes this change. Hardware acceleration is off, and using the same extensions (and more) on other browsers doesn't result in the same problem on those browsers. The problem is worst by far when I'm using YouTube.

I am a heavy Firefox user, and have been using it (and its predecessor) since Netscape. In the last year, the size of my Firefox profile has more than doubled, from 500MB to 1.3GB. What's the probable cause(s), and what can I do about it?

I am trying to troubleshoot a problem with high CPU usage by Firefox when using Mozilla VPN - VPN ON.. Problem occurs when starting in Safe Mode, and still occurs after performing Refresh. Problem can also occur just by changing to a new tab. Problem does not occur if Mozilla VPN is turned OFF. Problem does not occur with Microsoft Edge. Mozilla VPN Support said it is a Firefox issue, and recommended contacting Firefox if safe start or refresh did not help.

Hoping that someone can help me solve this issue. Thanks!

I'm tired of trying to find a solution to this problem, you're deaf!

I have been using Firefox since 2003. to avoid writing unnecessary words, I will simply state, I will leave firefox if you do not eliminate this problem:

firefox eats up all the RAM on my Mac. It is none of your business whether I open 1 tab or 10 tabs, give me the ability to limit the memory used by firefox, otherwise it eats up all the computer's memory.
