Mac OSX users can make Firefox look like Safari using the GrApple theme that can be found here : http://www.takebacktheweb.org/
Safari is a pretty good browser, still there are some people like me who would like to use Firefox (www.mozilla.com). Safari users who would like to move to Firefox would be at home after installing this theme.
How to Install :
Go to site : http://www.takebacktheweb.org/
find the Mac OSX theme you like. Just click on the “Install Now” button for the theme you have selected.
Other option : From Firefox ->Tools->Themes-> Get New themes; This opens a new browser window for the addons.mozilla.org site. On the search box, search for GrApple. You will get the Mac OSX themes for Firefox.
Note : These themes only work on Mac OSX. If you are on Windows, just get a Mac 🙂
