In a recent announcement, Mozilla revealed that it had acquired the startup Fakespot, 

whose browser plugin can detect fraudulent customer reviews.

With this purchase, Mozilla intends to further incorporate Fakespot's technology

 into Firefox to assist users in "cutting through false reviews [so they can] shop with the assurance 

 that what they're buying is high-quality and authentic," according to a Mozilla statement. 

If you didn't already know, the extension combines "artificial intelligence (AI)

 machine learning (ML)... internet reviews in order to find [common] patterns.
