This addon stopped working awhile ago. Can't find any replacement

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.

Doesn't work. I've restarted a session with many tabs. Clicked the addon icon to stop them from loading: they still load normally until being fully loaded.

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
