I have an older PPC G4 powerbook running Tiger 10.4.11 and Safari 3.1.2. Well, I'm finally getting messages that certain sites won't support this browser anymore, etc. No surprise there, it was bound to happen eventually. I need to upgrade, however, I'm leery of installing/upgrading anything that will slow my already sluggish computer down. Did a little search, and saw some posts that said Safari 4 was buggy when people upgraded (these were old posts, mind you, from when Safari 4 was first released). Did they ever work things out? What would be best/fastest on an older machine like mine. Thinking about Firefox or Chrome--if they offer a version that will work. Whatever is smooth and easy. Kind of hard finding out new information about old issues... I know I'm living in the past (I have a new MacBook Pro for most things), but I still use this old clunker for certain tasks, and as a back up, and I want to make any transitions from this life to the next easy for her. So, what browser works well on your old machines? I really appreciate your advice.
