Neil Lee has once again gifted the Mac community with optimized builds of Firefox 220.127.116.11. There are builds for G4s, G5s and Intel Macs. Bless you, Neil.
As if that weren't enough, Neil went ahead an applied Firefoxy to both the Intel and G4 builds (sadly you G5'ers will have to suffer with OS X form widgets only).
The downloads are free, but Neil suggests you call your Mom and Dad instead of donating to him.
