Does what it says on the can, however no support for other regions, in my case .au

I spend the bulk of my online shopping time from my phone. if there were a mobile ff extension would be a great option

La extensión es muy práctica,,,,

Love this add on but as other have noted, it is not currently working with Firefox 57+. Please fix!

I updated to 2.9.5 and now it doesn't work with Firefox 49.0.2. Running Windows 7 and I just get a white box.

Update - Went back to 2.9.2 and all is well again.

For the last week or so all I get is "An error has occurred." when clicking the button on an Amazon product page. The same page works fine on Chrome. The other extensions I have installed are Umatrix, Ublock Origin, and Fakespot.
