Atlivec-optimized firefox (link courtesy of javaman).
Like, HOLY SHIT. Visible difference. Tactile difference. From "slug on ketamine" to snappier than Safari. Not just UI, either- though UI is traditionally the area all Mozilla progeny SUCK ASS IN on the Mac (ESPECIALLY Thunderbird)- I'm talking the whole enchilada. My ancient crotchety nursing-home grade G4 2x450 actually feels kinna... snappy.
It's kind of confusing, since I'm used to it feeling like a 7100.
Now if only Firefox had non-gay bookmark management and non-gay download management. Then I could drop Safari and join the rest of the trendy non-gay trans-platform kids.
