Hi Firefox uses a lot of memory, for example, one tab use over 2 GB memory ! and for 3~4 tabs FF use >90 % system memory ~( 3.7 GB )!!! The MAIN PROBLEM is even after closing tabs firefox doesn't kill the related process and tab process is running. I should find tab process PID using "about:performance" >> Process and then kill it using TASKMGR.exe. So I think if FF close tab related process RAM space will be released. How can i solve this problem ?

Hello. In case you have an Intel graphics card (or in any case), make sure you use the latest graphics drivers - this question may be of help too. The same applies to other graphics cards, so also see the Upgrade your graphics drivers to use hardware acceleration and WebGL support article for more info and reference points.
