A “favelet” is a small jscript applications which are very easy to use. All you need to do is drag the selected favelet to your favorites toolbar and drop it there, which will create a kind of “bookmark” containing this javascript. These favelets can be used for validating HTML, CSS, translating pages with babelfish, view certain scripts etc. Favelets have become more and more popular lately since you can use them for so many different purposes, and there are a lot more than these ones out there.
