Put Safari 4 Beta’s Tabs Back
One of the changes in Safari 4 is that the Tabs are now located at the very top of the Safari window. If your not fond of Safari’s new tab system which has the tabs at the top like Google chrome, you can always change it back to the way you’ve always used. For Mac users at least.
Open up the terminal and type in:
defaults write com.apple.Safari DebugSafari4TabBarIsOnTop -bool FALSE
If you decide you want the Tabs back at the top of the Safari window, re-enter the command in a Terminal window but change FALSE at the end of the command to TRUE.
