Despite claiming they're a "privacy-first company", the add-on will collect your username on various sites, all the products you view, search history, and the products you buy.

They have the gall to say they will never sell any data, but it clearly states in the privacy policy they will use this collected information to market items, sellers, provide ads, and "Sharing personal information with third parties".

Abysmal.

It works as expected, but one star for forcing "Opt-in" on data collection. Your choices are to opt-in or uninstall. Opt-in means I have a choice. You have removed that choice, so there is no opting in. Either I accept the terms and conditions, or I don't.

This addon requires you to give your data to them for it to function, this is a gross violation of privacy and an abusive strategy to generate revenue from its users.

This works great - considering the fact that it has to interface with hostile 3rd party sites, it's amazing that it works as well as it does. Thanks!

This addon breaks "sort by lowest price" on amazon. Had to uninstall it just to be able to use that again.

I haven't used it enough to give it a full five stars, but in the spin around the block I gave it on Amazon it provided enough useful information to feel confident in choosing one product over another.

No longer functional

GOOD!

About 3/4 of the time the accuracy rating feels right, but sometimes its obviously wrong.

Awesome app Like getting information about sellers.

Was fine until Mozilla purchased it. I assume Amazon may have paid Mozilla to neuter the app. No longer sorts according to Fakespot score, no longer shows the Fakespot score on the search results page, no longer can eliminate the F scores.

Good job Mozilla, you're now part of the problem.
