"Adblock Plus is a Firefox add-on which prevents certain banners and other advertisements from being downloaded, and therefore displayed, when you visit a Web page. A fully customizable integrated filter gives you the ability to block specific ad types or to stifle the majority of advertisements altogether."
"Ever been annoyed by all those ads and banners on the internet that often take longer to download than everything else on the page? Install Adblock Plus now and get rid of them. 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 you select a filter subscription when Adblock Plus starts up the first time, then even this simple task will usually be unnecessary: the filter subscription will block most advertisements fully automatically."
