Noticed a suspicious element called give-freely-root-bcjindcccaagfpapjjmafapmmgkkhgoa in the chrome inspector today.

Turns out about a month ago, the popular open source [JSON Formatter chrome extension](https://chromewebstore.google.com/detail/json-formatter/bcji...) went closed source and started injecting adware into checkout pages. Also seems to be doing some geolocation tracking.

I didn't see this come up on hn, so I figured I'd sound the alarm for all the privacy-conscious folks here.

At this point, I feel like browser extension marketplaces are a failed experiment. I can just vibecode my own json pretty-printer extension and never deal with this problem again.

Before you continue

Thanks for posting this. I think it's such a shitty thing to do. I don't have much of a problem if an original author wanted to do a closed fork of an open source project, but to start injecting ads, without warning, to folks who have already installed your generic JSON formatter and phrase it as "I'm moving to a closed-source, commercial model in order to build a more comprehensive API-browsing tool with premium features." - seriously, f' off.

I agree that browser extension marketplaces are a failed experiment at this point. I used to run security an a fin services company, and our primary app had very strict Content Security Policy rules. We would get tons of notifications to our report-uri endpoint all the time from folks who had installed extensions that were doing lots of nefarious things.

We could use llms to scan source code and list all of the behavior not listed in the extensions page, like adware and geolocation tracking for example. Then another LLM locally to disable it and warn you with a message explaining the situation.
