Google Earth for Linux

If you right-click on an image, Firefox will offer to "block images from" the originating site. Useful for graphic ads, since they are normally served from specific servers; the image is downloaded (if you look carefully at the status bar you will still see a request to that server) but not displayed. Effective and integrated in the browser -- one of those nice little features Internet Explorer will never have.

Add to this not having the flash plugin, and browsing becomes a pleasant experience once more. (Text ads are shown, but they are normally unobstrusive and once in a while even useful.)

As to click-throughs on those ads, I have always thought that 90% of them are done by mistake. So the probability of an ad being clicked on is just proportional to its size. It still holds with blocked ads.
