According to this profile: http://people.mozilla.org/~bgirard/cleopatra/#report=8a51b9a8ecf10789eca95fd280cd11c1c0f08f46&search=fillTrailingGap the transitionend handler in tabbrowser.xml is calling _handleNewTab, which calls _fillTrailingGap, which gets the scrollposition of the tabbrowser's scrollbox, which causes a layout flush, which is slow. We should see if we can not do that.
