I've been a long time fan of AdBlock Plus, but until recently I haven't discovered the true power of another Firefox add-on - NoScript. The magic with this one is that the little Serpent removes all the JunkScript (err, JavaScript) from the page your are visiting, unless told otherwise. Thing that will break lots of sites in this web2.0+ world, but brings a bit more safety to your browsing.
There's also a helper add-on for AdBlock, which is Adblock Filterset.G Updater and handles the task of feeding up-to-date filters to it; What filters? (Internet) Ad removal filters, you'll see the sites as never seen before! :-)
Side comments:
- if you enable NoScript, don't forget to allow Google Analytics or other trusted visitor tracking engines outhere (be fair towards the webmasters)
- FireFox 3 Beta seems to be (a bit) more faster than FF2 and the support for 3rd party add-ons is growing; just take it for a ride if your time allows it
- hey, you have commercials/ads on this page! What?! I don't see any... do you still see them? :-)
