Is support for 'MMX' & '3DNow!' already dropped?

They do get the baseline

There are a couple of interrelated issues here.
Can we require SSE2 for Mozilla builds of
I think we need to admit that there isn't any rational, analytical way to
compare most of the costs here. The one number we *do* have, the number of
users who can't upgrade, is kind of tantalizing us, but we can't quantify
how many users we'll gain by requiring SSE2, how many other bugs we'll fix

More or less, yes.
I can't imagine any scenario were a user needs to run a Pentium III with GUI
and a browser on it...
There were AMD CPUs newer than that

N00b question:

years ???
