This is a handy add-on but it has the potential to be so much more convenient. Shortening the url should not have to open a new window or tab. If either the url shortened automatically in the address bar or simply was copied to the clipboard, foxy and I would get along so much better.
It would be nice to have a settings menu. Considering this add-on only use I see no need in the window showing me the shortened URL and then needing to press a button (two actually since it's in flash for some reason) to copy the shortened URL to the clipboard. I'd like to be able to just press the big F button and get a quick notice "copied to clipboard" so I could carry on with my life :)
Superb, on request the developer immediately updated website information about URL storage. URLs are kept forever. That's great and provides equal functionality as tinyURL then. And I prefer foxyURL, because "foxy" is just nicer in the URL to have :-D
