Does NOT work on Mac (fine on Windows) Rated 1 out of 5 stars

May 10, 2012 update to this post:

Installed version "11.0.20120505b" and works on Mac now.

NOTE: as of April 15, 2012 I have updated to Add Bookmark Here 2 - version 11.0.20120415 and Firefox 12.0 and I have the same problem as described below.

Is there a fix? Is there something I can do to make this work?
On Mac (OS X 10.7.x) it does not work at all with Firefox 10.x or 11.x.

I am using version Add Bookmark Here version 4.0.20120406

If you select "Bookmarks" from the menu, navigate to desired folder and click "Add Bookmark Here" NOTHING happens and no bookmark is added.

I really wish this would work on the Mac because it is excellent on the Windows box. If it worked on Mac I'd give it 5 stars.

This review is for a previous version of the add-on (4.0.20120406.1-signed).
