Great. Rated 5 out of 5 stars

Now we need a RightToSize to remedy Mozilla's (yet again) wrong-headed decision to prevent users from implementing javascript in bookmarklets to size/resize the browser window (which doesn't actually stop sites from doing it, only users). Thanks.

(Done :D. Fx16+: devtools.chrome.enabled -> true => now use Web Console to enter window commands.)

This review is for a previous version of the add-on (2.8.9).
