Nice - but blocks google maps on some websites (maps blocked on local.ch for example, using FFox 11 on MAC).
edit: see dev. answer (thanks), I have to correct my "but" statement above. more control means ... to control though...:-)
That’s the purpose of this add-on
Google Maps sends your browsing activity to Google. See the screenshots and instructions above — you can click the Google Disconnect icon in the location bar to unblock an embedded map and your preference will be remembered the next time you’re on the site.
