Users of Safari 4.0 beta may have noticed that after installing the SafariStand browser plugin, Safari immediately crashes when launching.

After a few months and many failed attempts at using the plugin, I decided to just delete everything SafariStand-related and reinstall from scratch. As it turns out, Safari was choking on the existing SafariStand preference files.

Delete these two files, and Safari will play nicely with SafariStand:

/Users/YOU/Library/Preferences/jp.hetima.SafariStand.plist
/Users/YOU/Library/Safari/Stand
