(In reply to Ed Morley [:edmorley] from comment #0) > * Subsequent tab operations (switching, closing etc) occur on the wrong tab Also: middle mouse click (to close) some of the tabs on either window - you instead sometimes get a new tab opened (as though you had middle clicked on an empty space on the tab bar).
(In reply to Ed Morley [:edmorley] from comment #0) > * Tab doesn't always drop at the correct location on the new window's tab bar I can't reproduce this. Please file a separate bug if you have STR.

Verified as fixed on Firefox 17 beta 1 - when moving a tab to a different window, there are no gaps left in the other window, the tab can be dropped in the wanted location and the tab operations can be properly done.
