Rated 5 out of 5 stars

Just a message to say all your work is appreciated and hope you manage to fix the problems for TB v60 and above. It must be maddening to have your work ruined by these constant changes to the main prog.
I have been sorely tempted to ditch Firefox as well on many occasions. I used to have many excellent extensions installed, which improved my experience with the program immensely. But one by one the Add-on developers got fed up with the constant battle to keep up with changes and gave up the fight.

This review is for a previous version of the add-on (3.0.0).
