Link Fixer

Make sure you have FireFox and GreaseMonkey.

The only thing you have to do is to install this script. To do this, just click here and click on "Install". Easy heh ? That's all !

Alternatively, you could use my Frame Remover (Idea : dantman), which, instead of fixing the links, removes the frame when it appears. The warning message appears in a pop-up instead, so turn them on.
