This script fetches the current open tabs in all Safari windows. Useful to run remotely on your mac when you are at work and want to read a page you have open (remotely) at home but don't remember the url but can log in to your home system on the command line

Thanks a lot! Also works with Chrome if 'tell app "Chrome" to {URL,name} of tabs of windows'

After so many years still works! just explicitly I had to use python2.
