No ... Rated 1 out of 5 stars

I had to move my selected bookmarks to a new folder, off of the convenient toolbar, AND the random favorite only opens as a second tab. Messy. And it won't work with restored pages. Good idea.. but needs to work through Firefox Options control panel, not separately.

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

partly agree

Partly agree - when session is restored tabsup doesn't open it's own set - one can use buttons but this behavior can be regarded as a flaw. As to moving bookmarks problem - it was better to copy them than to move, yet I'll think of adding favourite bar to listboxes in tabsup option window, thanks for this suggestion. But tweaking firefox's internal option window - I'm afraid you request impossible :)
