Unstable mem using
Firefox using rams abt 90% of ram capasity and it going very slow. If I have 4 tabs open and I open one more some firefox prosess can using 1.5 -2 Gt ram, all firefox prosesses take ram ant 3Gt. I look from win7 taskmanager. If I kill all firefox prosesses from taskmanager. Then I start firefox new time all earlier sites it take ram only 10%. I thinking mem free not work. You can wait long time ram situations keeped same abt 3Gt reserved.
