Great concept, but the bug everyone is talking about makes it unusable. A fork or update to fix that would be much appreciated.
For the record: in my case, if I exit Firefox with the left-most tab active, its URL will be copied to all other "restored" tabs when I re-open FF. Sometimes ctrl-z on the URL bar gives me the correct URL back, but not always.
Took me MONTHS to figure out this was the addon doing that.
Edit: https://addons.mozilla.org/en-US/firefox/addon/back-to-owner-tab seems to be a good replacement so far.
