I cant believe how well this works, and how liberated I feel:
It's an addon to Firefox that makes browsing the Internet ..well, just try it! I was hesitating, but wow!
I can go to a site like "killfrog.com" which normally hits you with heaps of popup adds and get nothing except what I want.
I can't speak much for the linux version except that my asus eepc came with some form of linux and it seems to work fine as well.
