Better yet, use K-Meleon on any resource constrained PC. It has a tiny footprint even with 15+ tabs, uses the same AdBlockPlus as FF and is based on the FF/Gecko engine. Triple win.
P.S.: I still recommend Opera if you have a decent PC.
Use ADMuncher...Its the best... It works on almost every app that has advertisements.
go to Ad Blocker Software - Ad Muncher and check out the trial version.
It costs around 1K Rs.
