I've been playing Facebook games for a while now and I've noticed na bumabagal yung browsers ko, both Firefox and IE, especially if sabay sabay kong silang nilalaro (Mafia Wars, Farmville, Restaurant City, Poker). May lag when I switch tabs or browser windows. May lag din kahit sa pagscroll sa page.

What should I do para bumilis browsers ko? Should I add more memory? Umaabot na kasi minsan ng more than 90% ang CPU usage ng Firefox.
