AdBlock Plus------ Cool Plugin.

I installed firefox and was searching through its plugins where i found this one Adblock Plus.

It just filters away the ads and banners on the internet thus increasing the browsing speed.. I really liked this one.

Its very Simple..
Right-click on a banner and choose “Adblock” from the context menu — the banner won’t be downloaded again. Maybe even replace parts of the banner address with star symbols to block similar banners as well. Or choose a filter subscription, then even this simple task will usually be unnecessary: the filter subscription will block most advertisements fully automatically.

Currently I'm using it with my Firefox ver. 3 and its working great. It comes for Thunderbird and SeaMonkey too.
