I've been using every browser other than safari for the past few years. (Firefox, Chrome, and Opera). I recently switched back to safari after reformatting my hard disk. The extension Ad Block Plus which worked extremely well in Opera and Chrome, is now giving me problems in safari. I never had to worry about Pandora ads, Youtube ads, or any kind of random pop-up. It just worked perfectly. In safari I will randomly get youtube and pandora ads with this extension. (Using the default Flash youtube.. not HTML5) Is there a better extension for safari? I like using this browser because when on the battery it seems to stay a little cooler and I get a little more battery life compared to the other webkit browsers.
