I noticed the difference in Safari 6.0 in Lion and Mountain Lion. In Lion it is Safari v 6.0 (7536.25) where as in Mountain Lion it is 8536.25.. The way safari works is also a bit different, for instance the tab view. I liked it when I used it, but I want the same in my Lion as well.. Can I copy the Safari.app from my office laptop running Mountain Lion and put it in my 13" MBP running Lion? Would this work?
