In this case, Microsoft is staying classy. Mozilla, just barking to be the loudest dog on the playground. Sad...
I think a more true, yet less controversial statement from Mozilla would be, FF 4 will leave IE9 (and FF3.6x) in the dust with respect to standards conformance.
I'd even agree with that. But saying that IE9 is not modern seems dishonest.
But the argument that a version of IE which hasn't even come out yet doesn't have features that other browsers have had for years are valid points.
I guess "IE9 sucks" was deemed not to be tactful enough.
