Stopped working after a recent Firefox update Rated 1 out of 5 stars

I would have given it a 5 star, but I've been unable to use it for a couple months and the developer didn't respond to support emails.

This review is for a previous version of the add-on (2.2.1-signed). 

Not working in Windows 10 Rated 1 out of 5 stars

When I click the widget icon in the toolbar, nothing happens. I just upgraded to Windows 10, so don't know if there's any kind of incompatibility issue with the widget in that environment.

Excellent for FBA Users Rated 4 out of 5 stars

This widget is great for determining the profitability of items to sell on Amazon for FBA sellers. I use it all the time! Thanks!
