Ye' old general discussion board. Basically, for everything that isn't covered elsewhere. Come here to shoot the breeze, shoot your mouth off, or whatever suits your fancy. This forum is not for asking programming related questions.
I'm still waiting for someone to get IE to run stable in Wine. I know it does run in wine and will do the updates etc but it was very buggy last I checked. Crossover office did it but I don't think it's worth the money after the free trial i had.
That Firefox extension looks pretty cool for windows though
i might be wrong because ive never tried FF but i presume it's for use with websites such as the microsoft one in the pic on that site which will probably have been programmed with only IE in mind.
