Well the title sounded neat and I gave it a try. It did not work so I emailed the creator they got back to me and I gave it another try. You can not have sub folders in your applications folder like me or the program does not see Safari. I drug Safari out of my sub folder and the program worked. I love the print and tabs buttons and not lose any other buttons. I don't know how I lived with out it before. Funny story my step-brother visited for the weekend and told my how his windows computer now has taps and I said yeah I love how my Safari has tabs and now extra buttons. I think he was just a little jealous. Keep up the good work. I love it free. Thanks.
