For your downloading pleasure, Flip4Mac 2.0.2 is here (upgraded from 2.0.1) Claims to offer "more support for websites and browsers" (previously, Flip4Mac was officially Safari only) Doesn't say which browsers, but I would presume that Firefox is a likely candidate. Haven't tried it yet on FF. Since Flip4Mac's browser plug-in is still a work-in-progress (something the Flip4Mac folks acknowledge and actively tweak along the way) I would expect more updates in the relatively near future as they iron out code compatibility with various website implementations of Windows media. Once again, sorry Universal Binary fans, but it's looks like it's still PPC. Flip4Mac has said in the past that they intend to release a UB version soon.
