Rated 1 out of 5 stars

This review is only for the current version of this addon which sucks bigtime. As other reviewers say, the addon mixes up the history of various tabs about 10-20% of the time(particularly when we restore a session). This has led me to lose data a number of times.

There was a time when I was on Firefox 8 or 9 when it used to work perfectly. I used to consider this addon indispensable and eve added to the addon collection of "Stable and Non Conflicting addons" I have made.

Alas, it couldn't stay that way. And the developer doesn't seem like he is paying attention. Gotta look for a replacement.
