Bookmarks to open in new tab functionality lost Rated 5 out of 5 stars

Bookmarks to open in new tab functionality induced by TMP and Piro's extension is broken as result of conflict with imacros extension in firefox release candidate Firefox/21.0. My IP is blocked hence cannot report on support site.
Edit- Fixed http://www.iopus.com/download/imacros-8.51.xpi

This review is for a previous version of the add-on (8.3.0).
