i'm running a mid-2011 iMac under 10.6.8 and have Safari 4.0.5 (6531.22.7) installed. Anyone know which newer version of Safari I SHOULD be running? And If i wanted to install a version of Firefox, which one? BTW ... what's the "(6531.22.7)" after the version # of Safari refer to? I also use an older version of Pages 4.0.1 (746) - any update to this i should consider? Thanks.
