Rated 3 out of 5 stars

As far as I can remember, I've never had reason to register here for a comment. The reason was simple .... Firefox WORKED. It's sad when the reason for finally registering to make a comment is because Firefox NO LONGER works ... at least not as good as once did.
As with several reviewers here, I only just now upgraded from 3.6. I stayed with that version so long beause of the same reason above, it WORKED. But obviously it was dated, so a growing number of apps were fighting with it.
Thus I finally upgraded to V12, only to immediately find the MOST useful bar on the browser has been trashed, forcing use of a CPU/RAM-using add-on to get the same function as the browser once had.
1 step forward, 2 steps back. I HATE changing browsers, but this type of short-sighted foolishness is what caused me to finally drop a ONCE great browser about 6-8 years ago. Everyone else did too, as the entire project folded 3 or 4 years ago.
Thanks for the add-on. Hopefully it will bring back the usefullness which should never have even been considered for deletion in the first place. If not, I'll probably be forced to go shopping again.

This review is for a previous version of the add-on (2012.07.08.17).
