Spell checker and the forum

aka

I have AI Spell Checkeer installed in FIREFOX (which is my primary browser). I use many other forums, but this one does not allow me to use it. It is simply not working. This drives me nuts.

I assume there is some code on the page that disables FFOX extensions or alike. I would like to hear if somebody else have this same problem, or is it just me ?

As far as I know then the forum software used is Vanilla Forums so if you want to know if it is a general problem with Vanilla then you can check against that.
