It was my most useful extension Rated 4 out of 5 stars
Broken in FF22 (as many others have already noted). I've reverted back to FF21 because this extension has become indispensible in my workflow (due to the way I use history to track things). I hope the author fixes it soon as I would like to take advantage of using newer versions of FF as they become available..This review is for a previous version of the add-on (0.11.5.1-signed.1-signed).
Bug fix in the pipe
The bug has been reported and identified (see https://www.mozdev.org/bugs/show_bug.cgi?id=25479), and the fixed version is currently reviewed by Mozilla. It should land here within a few days.
Thanks for your confidence and your patience.
