I'm not sure if you are aware but if you take out the browser variable AHK automatically sends urls to the default browser when you send
[copy or print]Just edited your script (took out all references to "browser") and the fox ran it beautifully.
One other thing that you might want to include is Google Feeling Lucky I use this all the time
Your %22's around the google search would not be optimal were you to include the feeling lucky search in your script. Also when you use the compiler thats bundled with AHK you can chose your icon file there (Currently only works with Compiled scripts)
