Comment 84 for bug 66566

Yes, fair point.
I'm not saying that my muscle memory should take precedence.

I think the points about internally consistent behavior and matching behavior of other browsers are more compelling.

Maybe upon hitting cmd-enter, FF could detect whether the entry was in need of .com completion, and perform whatever action accordingly. There is some logic in place already to determine whether or not to append ".com": when i enter mozilla.org and hit cmd-enter, my request isn't transformed to mozilla.org.com
