Works great, but broken in Minefield Rated 5 out of 5 stars

This is an indispensable addon for those of us who like to see the full contents of a page title as we control + tab through our open pages. However, it's breaks the Firefox button rendering in the most recent nightly builds - the menu button is twice the height it should be.

This review is for a previous version of the add-on (1.2).  This user has a previous review of this add-on.
