It works. Often you will have to click it more than once, but thats a minor inconvenience, and i dont think its this addon's fault anyhow. its just mozilla being a little stubborn. Great addon. Highly reccomend for users who come back to firefox as they left it; with dozens of tabs opened, to come back to. Cool the floodgates, with this one.

this is gonna be my No. 1 FF extension from now on!
EVEN TABMIX PLUS DIDN'T HAVE THIS FOR YEAAAARS!! (WHY??)
i really start loving these new compartmented extensions (or at least they seem to be).

Useful if you do not want all the pages beeing (re)loaded
