AppleScript Programming/Sample Programs/Safari Quit Warning

Note: This script is obsolete for its purpose, since by these days Safari prompts user for confirmation if there is more than one window/tab open while quitting. But as the code itself is valid, it may be kept as a general example.

This is quite much doing same than Firefox's alert box that pops up when you're about to quit the browser with more than one window/tab open.

I use external tool (iKey) to force this script to be run when cmd+Q is hit while Safari is active application. I just plain hate it, when I mispress it instead of cmd+W or opt+Q.

(*
I made the code ignore window "Downloads", as it is relatively
irrelevant, especially since Safari already alerts if you got downloads
going. Plus, if you once open that window, Safari will count it open
even when you close it - until you quit Safari.

If you don't use English as OS language, then change it to represent
the window name in the language you use - in variable setting just
right after this note ends - if you want to (not necessary if you
don't care what counts the alert gives).

Enjoy your browsing. :)
