1. Safe mode to Firefox
2. To install one add-on
3. I will confirm that the new toolbar disappears

I repeated 2 and 3.
I have to install this add-on.
Then,
"New Toolbar" had disappeared.

Phenomenon that occurs with a probability of 100%.

This review is for a previous version of the add-on (1.1.2). 

I think I can finally reproduce and confirm this bug thanks to another similar report. I wish this issue has been reported on the support forum which would allow me to quickly reproduce it. Bug has been added to known issues.

Thanks for your review.

UPDATE:
This bug is now fixed.
