Rated 5 out of 5 stars

addon performed well for 30 minutes, but after laptop restart shows blank window. Re-install / update does not help. Firefox 51.0.1 64 bit. However server part (price drop notification) works fine. Support team has restored plugin operations in 12 hours. Excellent.

This review is for a previous version of the add-on (2.8.2). 

This problem should be fixed with the next version of our extension, currently under review by Mozilla.
