I know there are tons of lists like this, but why not add my own to the soup? It’s not vastly different from most lists, but I’ll try to boil it down to as few as possible to address security and annoyances:
- AdBlock filters out ads on a per-site basis. Plus, you can select individual elements in a web page to be filtered out.
- AdBlock Filterset.G Updater automatically downloads a list of ad sites which are to be blocked.
- Greasemonkey is more of a “meta-add-on” in the sense that this add-on allows you to write scripts which modify any web page you browse. The most useful one I’ve found, just because I’m on MySpace a lot, is the style remover. It gets rid of all the headache-inducing pimping on people’s profiles.
