Comment 56 for bug 438868

Alright, noticed a couple more things about what happens when Firefox gets in this mode:

1) After selecting all of the text in the url bar, mousing out of the window (like moving your mouse over the title bar) will unselect everything in the url bar, much like what would happen if you focused another window.

2) After clearing everything in the address bar, mousing out of the window will show the emptytext ("Search Bookmarks and History"), much like what would happen if you focused something else.

Focusing another window will take Firefox out of this mode.

This problem is really not okay for Ubuntu users.
