i can't recommend this extension honestly. a lot of reputable brands/products I know are getting low ratings. It's hard to trust what it says.

Used to be good. *Used* to be. Cannot trust it anymore. Sites that I know are scam sites are given As & Bs, while other sites that are reputable are given Ds and Fs. Uninstalled.

The tool has been useful. I am glad I've found this add-on. Tried the AI bot tool, it shows good summary to my questions and saves me quite a tons of time by going through the review details.

Used to be helpful, now is completely useless. AI bots have broken this tool.

Contradictory and bad info. Sellers I've used for years (and are good) ranked D but super sketch sellers get an A with 3 reviews and only being open for a few months.

The real killer is it runs on websites it has no business on. Like it runs on everything rather than looking for qualifying commerce sites. It just injects itself into everything breaking local web services like router and networking panels, snooping on banking or anything else you do...Mozilla somehow manages to push the boundaries of bad decisions when they were supposed to be the good/safe/privacy respecting alternative...yet here they are feeding all our habits to another LLM/ML/Ai...

I installed this on 2 different systems. The first I was never shown the forced opt in privacy panel. It wasn't until the second install that I was presented with that...So the install process can / does / is broken in a way you can give up your right to privacy without knowing what it's doing. Despite that if you do opt in (the only way to use it) and start to dig a bit you can see it's broken, intrusive and should not be trusted.

As a side note when uninstalling I noticed conveniently you can't report it for abuse...funny...

so far I am not impressed. reports products with an A rating with only one rating but no review. reports 50% deception on an item I reviewed when there are only 6 reviews one of which is not a vine review. does not point out which reviews are "deceptive" reports products with lots of deceptive or badly written reviews with an A rating. list pros and cons by quoting partial sentences from reviews. asks for feedback on it;s webpage but does not allow you to write why you are clicking thumbs up or down. seems no better than flipping a coin.

Removes Sponsored listings in the search results but adds it's own ads in the item pages themselves.

Privacy concerns, do not install because this extension tracks your browsing (I have reverse-engineered their minified js code and everything you visit is caught and sent to their servers including your browser, your mouse clicks (using sentry.io) and your urlParams (which contains lots of useful information (UTM for example)))

A nice to have that helps you avoid scams but emphasis on "helps". It's just one tool but not a replacement for doing your own research. You can't rely on it alone.
Really nice to know this extension is now owned by Mozilla but they need to put the "Recommended" seal next to it if Mozilla wants to show they have faith in it.
