CloseReview for Compact Menu 2 by Richard Foulkes
Rated 5 out of 5 stars
Yes, this extension on AMO currently breaks a number of basic bookmarking features.
But Frank Lion has a couple of versions of the same extension and they do not break bookmarking.
He has them named Compact Menu3 (two display versions)
