I love to use tabs in Safari. I find it much better then having 10 or 20 windows open for each website I am using. In Safari 2 there was a checkbox in the Safari Tab preferences, but it’s now missing from there. A quick Google lookup turned up a nice hint on MacOSXHints.com. According to the hint you have to find the Safari property list and hack around a few strings. Sounds like fun, huh?!
Fortunately someone left a comment with a much easier solution. Just go to the View menu and select ‘Show Tab Bar’. Now that sounds a lot easier!
