Maybe I didn't give it enough of a shot, and I admit it's been a while. I tried it for a short time, but occasionally ads would get through, or blocked ads would screw up the layout of the page, or it would just be slow as shit.
AdBlock and AdBlock Plus are two different extensions. You can use them both. If you do, especially with Chrome, no ads. Been liking Chrome since I switched from FF about two years ago.
