'Compatabillity problem' says a compatabillity checker here.

I use FF for the extentions, but witht updates etc. often something breaks.... Which I do hate very much I have to say. Ik makes me give the browser a maximum of 6 on the scale from 0 (bad) to 10 (great). When one has to work with tings...
