I wonder if there is a Firefox add-on which simply removes the ads from a page. It would solve not only the problem that my friend had, but also a more generic one. Imagine it would be possible to browse ad-free, that should be really awsome.
The ad removal plug-in could be trained by users to detect ads, e.g. served by Google:). All the information about where the ads or banners are could be stored in some public database, and the plug-in could leverage the collective knowledge of all Web users. Considering that ads are normally served as:
- inline images or text
it should be rather easy for a browser to simply remove some pieces of HTML from the DOM or put them somewhere at the bottom of the page so that they don't disturb the eye.
