Firefox 4 received quite a bit of fanfare when it finally rolled out of beta. Unfortunately for some Mac users, Mozilla decided to drop support for PowerPC processors and therefore Mac OS X 10.4 Tiger from FF4, meaning that G3, G4 and G5 users were left out in the cold. If you're one of these users lovingly still using PPC Macs, the folks behind the Mac Classic browser, Classilla, have come to your rescue and brought Firefox 4, with nearly all the trimmings, to the now discarded Mac architecture.
