January? Seriously? Rated 4 out of 5 stars

Would get 5 stars if updated faster.
*update*
Installed the dev build and it apparently works fine. I wouldn't have updated to FF17 if I had known this add on would break. I hate the rapid release cycle so much. Heads at FF should roll.

I was shocked by how much of tab mix plus affects my browsing. Wouldn't even use FF but for TMP.

This review is for a previous version of the add-on (0.4.0.3.1-signed).
