Firefox is the best. I have Adblock Plus, NoScript, and Foxmarks Bookmark Synchronizer addons installed. Advertisements really bug me, especially flashing ones. With NoScript and AdBlock, I no longer see any advertisements. I can’t use any other browser now, I’ve gotten so spoiled.
I’ve been using the beta 3 for a couple of weeks now....I like it.
NoScript is a pain in the behind when you also have Stumble. I found it extremely irritating to have to do so much work to view items that came up on pages I stumbled onto!
