AdblockPlus makes life in the interwebz so much more bearable. Goodbye to youtube ads too.
The ads that really annoy me are the ones that pop up in videos despite me having Adblock activated. It doesn't happen most of the time, but on certain video players, such as Joystiq's, they somehow bypass it. And it just so happens that their ads are the really, really annoying kind that bring you to their page
when you click the exit button on the ad.
But otherwise, Adblock Plus is a godsend. I make sure to unblock it on websites that I want to support though, after all I am taking away potential revenue by blocking their ads.
