One great thing about Mozilla & it's tab browsing capability is you can set the middle mouse button (or wheel click for people lacking real buttons ;p) to open tabs in the background. So I pop up a forum and can then click on all the topics I'm interested in and by the time I tab over to them they are all loaded already. Works great on slashdot and other sites too. Don't think I could ever go back to non-tabbed browsing...
