LinkedIn is searching your browser extensions

Re: LinkedIn is searching your browser extensions
#222The 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…
> this is why I run ad blockers. It's pretty wild that we live in a world where the actual FBI has recommended we use ad blockers to protect ourselves, and if everyone actually listened, much of the Internet (and economy) as we know it would disappear. The FBI is like "you should protect yourself from the way that the third largest company in the world does business", and the average person's response is "nah, that w…

#223> Microsoft has 33,000 employees and a $15 billion legal budget
Microsoft has more than 220k employees (it's hard to follow with all the layoffs), and the G&A in which bankrolls legal expenses (but not only - it also contains basically every employee who's not engineering or sales) was only 7B in 2025 - so legal budget is much lower than that.

#224>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.
This is incredibly normal language and quite close to how I would write this quote, so what makes you think this is LLM text?

> this is a massive violation of trust This is not. To violate trust, there should have been some.
There's an implicit trust that a site doesn't try to racially profile you, as it is illegal. There's no enforcement, but that's why trust is being violated.

LinkedIn's scanning for browser extensions used by protected groups allows them to provide illegal services to US-based recruiters. I have no idea if they actually do it or not, and am not a lawyer, but common sense suggests there's enough here for a class action suit to move into discovery.

#226It seems to not scan for Privacy Badger and uBlock Origin, two extensions I rely on. That's...surprising.
Re: LinkedIn is searching your browser extensions
#227I don't like any of this, but I'm not totally clear how this is substantially different from other fingerprinting technologies which I assume are used by every large tech company. Could anyone elaborate? The post isn't very clear why this is different from other data surveillance.

> What business is it of LinkedIn's what browser extensions I have installed? The list of extensions they scan for has been extracted from the code. It was all extensions related to spamming and scraping LinkedIn last time this was posted: Extensions to scrape your LinkedIn session and extract contact info for lead lists, extensions to generate AI message spam. That seems like fair game for their business.
And instead LinkedIn is scraping all users computers?
I think it’s kind of funny that HN has gone so reactionary at tech companies that the comments here have become twisted against the anti-spam measures instituted on a website that will never trigger on any of their PCs, because HN users aren’t installing LinkedIn scrape and spam extensions.

How is probing your browser for installed extensions not "scanning your computer"? Calling the title misleading because they didn't breach the browser sandbox is wrong when this is clearly a scenario most people didn't think was possible. Chrome added extensionId randomization with the change to V3, so it's clearly not an intended scenario. > vs. something inherently sinister (e.g. “they’re checking to see if you’re…
> How is probing your browser for installed extensions not "scanning your computer"? I think most people would interpret “scanning your computer” as breaking out of the confines the browser and gathering information from the computer itself. If this was happening, the magnitude of the scandal would be hard to overstate. But this is not happening. What actually is happening is still a problem. But the hyperbole underm…
> To reiterate, at no point am I saying this is good or acceptable. I think there’s a massive privacy problem in the tech industry that needs to be addressed.
These two sentences highlight the underlying problem: Developers without an ethical backbone, or who are powerless to push back on unethical projects. What the article describes should not be "what many devs would land on" naturally. What many devs should land on is "scanning the user's browser in order to try to fingerprint him without consent is wrong and we cannot do it."
To put it more extreme: If a developer's boss said "We need to build software for a drone that will autonomously fly around and kill infants," The developer's natural reaction should not be: "OK, interesting problem. First we'll need a source of map data, and vision algorithm that identifies infants...." Yet, our industry is full of this "OK, interesting technology!" attitude.
Unfortunately, for every developer who is willing to draw the line on ethical grounds, there's another developer waiting in the recruiting pipeline more than willing to throw away "doing the right thing" if it lands him a six figure salary.
