This tip may have been posted already, if so i apologize but I havn't seen it here. One of the new "features" of Safari that has been driving me insane is the fact that it always re-opens to whatever pages were opened when it was last quit. I understand that lots of people may like this but I can't stand it and the fact that the feature does not have an "off" button drives me nuts. After scouring the Library folder to find out how to kill it, I finally found a solution, albeit a little "hacky". The issue comes not from safari itself but from a new lion feature called "saved application state." To prevent Safari from using this feature I did the following: 1. Launch Safari and navigate to whatever site you wish to open every time it is launched (e.g. I like to use Top Sites) 2. Quit Safari 3. Navigate to ~/Library/Saved Application State 4. Right click com.apple.Safari.savedState and select get info 5. Change permissions to read-only Thats it, now whenever you launch Safari it will use the page you selected and whenever you quit, it will not be able to update the save state because the folder in now read-only.
