I don't have any plugins installed. I have installed the 1Password extension for safari. Also I repaired my disk permission and this was in the log.

1Password version 2.X needs Safari to run in 32 bit mode.
1Password version 3.0b works OK with Safari in 64 bit mode.
Get Info on Safari in Finder and change to 32 bit if necessary.

Not much difference between plugins and extensions 🙂

I do not think the 1password extension is the problem. I removed the extension and restarted the mac. I closed safari and it still restarted.
