Remove dependency on Firebug #1
Description
According to http://getfirebug.com/
The Firebug extension isn't being developed or maintained any longer. We invite you to use the Firefox DevTools instead, which ship with Firebug.next.
See also Migration from Firebug guide.
Since we're being encouraged to use the Firefox Developer Tools instead of Firebug, we'll also have to drop usage of this extension. Would love to continue using this!
