Started using Phoenix as web browser. It's very light weight, supports java, flash, tabbed browsing (very cool feature!) etc, and has a configuration option saying: "Reject popup windows". What more can one want? Check it out on their website. Binaries for Windows, GNU/Linux etc. Very very easy to install. Just unpack and doubleclik on the phoenix.exe file... (yes, I admit it: I'm running Win98).
