This is incredibly normal language and quite close to how I would write this quote, so what makes you think this is LLM text?

It’s the fake drama. Punchy sentences. Contrast . And then? A banal payoff.

You're absolutely right.

The headline seems pretty misleading. Here’s what seems to actually be going on: > Every time you open LinkedIn in a Chrome-based browser, LinkedIn’s JavaScript executes a silent scan of your installed browser extensions. The scan probes for thousands of specific extensions by ID, collects the results, encrypts them, and transmits them to LinkedIn’s servers. This does seem invasive. It also seems like what I’d expect…

Your post sounds like "it sounds bad, but it's no different from what others do, so it's not that bad."

I would put it more like: it sounds bad, and it's no different from what others do, so they're all that bad.

The fact that they're working around an API limitation doesn't make this better, it just proves that they're up to no good. The whole reason there isn't an API for this is to prevent exactly this sort of enumeration.

It's clear that companies will do as much bad stuff as they can to make money. The fact that you can do this to work around extension enumeration limits should be treated as a security bug in Chrome, and fixed. And, while it doesn't really make a difference, LinkedIn should be considered to be exploiting a security vulnerability with this code.

>The user is never asked. Never told. LinkedIn’s privacy policy does not mention it. OMG is literally every article written with LLMs these days I just can't anymore. It's all so tiring.

I get it — it can be frustrating to encounter so much low effort AI content these days. But I think it’s worth looking at the bright side here: the increase in our production of entropy from GPU consumption will hasten the heat death of the universe. Would you like me to suggest some AI summarizer tools you could use to more efficiently read AI generated content in the meantime?

Nice try, but you em-dashed like a filthy human. The drone has been dispatched.

Firefox-based browsers not affected.

Hmm I opened linkedin in Firefox and ublock origin showed it blocked 4 items... then switched away and back and the counter was up to 12. Is that enough blocking, I wonder?

Firefox uses randomised IDs for installed extensions, so the method highlighted won't work on Firefox. That's not to say they aren't trying other methods on Firefox.

Why don't we train LLMs on the entire internet every day? Then we don't even need to read anything. Reading is something people did in 2025

There's nothing to patch, scanning is not possible. It's either the extension's choice to become detectable ("externally_connectable" is off by default) or it makes unique changes to websites that allow for its detection.

If it were just a matter of detecting changes to the DOM then this could only detect extensions that alter the LinkedIn website itself. I agree that would be much harder to make undetectable, but this seems like it goes beyond that.

As mentioned, there's a way to expose your extension to the web even without making changes. The other way is a key called "web_accessible_resources".

All of these are opt-in by the extensions and MV3 actually force you to specify which domains can access your extension. So, again, each extension must explicitly allow the web to find it.

I get the point you're making, but to be clear, "they’re checking to see if you’re a Muslim" vs "they’re checking to see if your fingerprint matches that of known Muslims in our ever-expanding database" are not too far off.

The next step for a forensic investigator, is to found out how many of those extensions, are actually from a partner or fully owned subsidiary from LinkedIn... When you see a cockroach...
