Hi everyone, I'm running 10.4.11 on my TiBook 1GHz with 1GB ram from OWC. The computer has 38 charge cycles on the original battery. That should give you some idea of how little use the computer has seen. I've experienced recurring kernel panics that look like this while using TenFourFox: The app also crashes like crazy. Safari 4 may be slow and CPU-intensive, but since going TenFourFox-free I've also been crash free. I ran an extensive Apple Hardware test which reported everything OK. Has anyone else experienced kernel panics relating to TenFourFox? Is this normal? I thought only kernel extensions or memory issues could cause them. Thanks!
