Rated 2 out of 5 stars
Great Add-on, but the developer seems to be a little slow to support new Firefox firmware. This seriously puts a dent in the usability of the add-on, since it breaks every time Firefox updates, and doesn't get fixed for months.
If support for the add-on can overcome this issue, however, it is a wonderful piece of work. It is unfortunate that in this case, the support is what drags it under.
