I'm curious to see what Mozilla will do with the shopping assistant portion. Lots of browser extensions, and potentially even some of the Mozilla sponsors offer these types of features, and if Mozilla just stamps them out all at once by integrating that feature, it might lose them some financial support.
On the other hand, I do hope they don't start amassing huge amounts of training data from their uses. It would be a real bummer to not have a decent browser option anymore.
I've already been using the fakespot extension for a few years, and honestly, it feels pretty useless. I've seen it give A and B scores for products that I know have fake reviews. And on Amazon or Walmart and similar sites, we already know that the reviews are bullshit, so what difference does it really make for it to tell me that? It's not like I have any better option in most cases.
Eh, Fakespot has been decent enough for me. I think it works best when there are a lot of reviews, it's not very helpful when it's like 5-10 reviews on a product.
I think the Keepa price tracker is far more useful for buying on Amazon if you're already cool with purchasing weird no-brand Chinese shit, although I do find myself just ordering from Aliexpress a lot more lately. Spend even less, wait a bit longer, but get the same shit.
