Make Safari open new windows in a new tab
Written by Brent Sheets

Firefox Preferences has a convenient option that forces all new windows to open in a new tab instead. Safari has a similar option but requires holding down the Command key. This Terminal tweak enables Safari to work like Firefox by automatically opening all new windows in a new tab with a plain click.
Warning! Do not experiment with Terminal commands or instructions. If you don’t understand what a Terminal command does – then don’t use it. It is extremely easy to trash your system settings using Unix commands. Consider yourself warned.
defaults write com.apple.Safari TargetedClicksCreateTabs -bool TRUE
Entering the same command but changing the “TRUE” to “FALSE” will restore the previous settings. I’m currently using Safari 4.0.1 (5530.18) at the time of this writing.
