Ok... 1. Apparently Rushmore doesn't know flash works with Firefox: "...that works with Flash content beyond Youtube. Firefox works with nothing else, with the one bonus being no Flash ads..." Well, it works for at least some stuff besides YouTube for me, including unfortunately, ads. 2. On YouTube, playing the same videos for comparison, Firefox works just as well as MicroB for me. 3. I don't find flash performance in general with either Firefox or MicroB much better than barely acceptable, but I don't see very much difference either. 4. It's Firefox now with the 1.0 release. Fennec was the devel code name.
