January? Seriously? Rated 4 out of 5 stars
Would get 5 stars if updated faster.
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.
