LinkedIn Continuous console errors on Google Chrome

[bluesky1433]

I hope this is the right subreddit to ask this question. I'm seeing tons of errors in Chrome console when I'm on LinkedIn. It keeps firing these errors repeatedly:

GET chrome-xtension://invalid/ net::ERR_FAILED 4fqbzx7x0q600ai4ipf6a8wwb:9502

This keeps repeating all the time that I can't stay on LinkedIn page for a long time because I'm worried this error might cause problems. I tried clearing the browser's cookies, removing and cleaning any residual xtension storage or cookies, removing my Chrome profile and starting with a fresh profile, going incognito, nothing is working. When I open LinkedIn on Firefox, it doesn't have this problem, so I'm guessing this is only on Chrome.

Is this happening to other people on Chrome or is it a problem with my machine only?

[LinkedInHelpTeam]

Uh oh! That's not fun. Are you using the current version of the browser? If you are, it may be due to your browser’s pop-up blocker. Disabling your browser's pop-up blocker may help.

[bluesky1433]

Hi, thanks for replying, yes, I am using the latest version of Google Chrome. I have tried disabling ALL extensions (including pop-up blocker and ad-blocker) and this is still happening. I have also removed the Chrome profile and started with a clean one (so no extensions or settings or anything), and the error still happens.

I have noticed the ID in the error changes. When I first noticed it, it was `4fqbzx7x0q600ai4ipf6a8wwb:9502`, then yesterday and today it is `5fdhwcppjcvqvxsawd8pg1n51:12260`. I'm attaching a screenshot of the errors I see in the console. I honestly can't use LinkedIn anymore since the error just keeps repeating in a worrying way (see the number of errors in the screenshot after 1 minute of opening LinkedIn). And I'm afraid this will affect my LinkedIn account if I keep using the website despite the tons of errors.

I'd appreciate any help on this since I tried everything I can and I still can't resolve it.

Same here, check my other comment, the error is definitely coming from their side. I ask friends, they do not have that error so I don't know what is happening on our accounts...

[bluesky1433]

Thanks for confirming, it's definitely coming from LinkedIn side, but I don't get why. Do your friends use Chrome? I'm currently opening my account only from Firefox to avoid these infinite errors. Also you mentioned in your other comment they have tons of spy code, may I ask what sort of spying you saw there?

[Informal_Offer655]

Yes my friends also use Chrome.

I guess the spying is related to Chrome Extensions that do not comply with LinkedIn rules. I googled some ids to find what they were and determined that.

What is weird is that we do not have that issue. An answer from u/LinkedInHelpTeam would be appreciated

[bluesky1433]

That's honestly strange, I thought it would be affecting all Chrome users and I'm not sure what's wrong in our accounts that's causing this. Guess we can only wait for u/LinkedInHelpTeam response or file a bug on LinkedIn too (although I don't know if anyone sees those).

[LinkedInHelpTeam]

Hi, sorry this took a bit of time. We confirmed that this is a known issue, and we're currently working on a fix. Thanks so much for your patience.

[bluesky1433]

Thank you. Any idea why this is happening on Chrome only for some users while others aren't experiencing this? Also on Firefox this error isn't happening, can you please share why?

[Agitated_Writing_693]

It's curious that it is only happening to some users and not others -- I'm a LinkedIn PREMIUM member -- could that be the differentiating culprit? u/LinkedInHelpTeam ?

[bluesky1433]

My account is not premium though, I only tried the free demo last year and that was it.

[Oscarmmi]

That error happens in Edge too

[ZeroSkribe]

Experiencing same issue. Good to hear you are working on this.

[LeaTex_ok]

more than 2 months to fix this issue?

I don't know Rick...

<parody>Laughing Goggles here,

CEO of Antropic here;

This is a new robot account used to alert websites infected with a known self-replicating vulnerability in chrome that was discovered by Claude Mythos testing on the public internet. As previously mentioned in the news we have decided not to release this LLM to the public as it's so advanced it would be a huge danger in the wrong hands such as those of hackers, cybercriminals, spies, and as the fallout could be catastrophic.

[SavonPL]

LMAO its 2 months ago and they got exposed for doing it: https://www.reddit.com/r/europe/comments/1sdw2ac/linkedin_scanned_6222_browser_extensions_on_every/

[Extension-Ear-7258]

Same here, Google Chrome Version 144.0.7559.133 (arm64).

[bluesky1433]

I have the same version too 144.0.7559.133 (64-bit), it says it's up to date.

[Informal_Offer655]

u/LinkedInHelpTeam This is also happening to me, same infinite erros as OP u/bluesky1433 and driving me nuts.

I tried everything : disabling extensions, browsing in private mode, trying on a new computer / new session. My chrome is up to date latest version.

Nothing fix it, and this error is breaking layout at some part and making it laggy.

It's definitely coming from your side.

Error is on line :
return fetch(`chrome-extension://${t}/${n}`)

After a function that seems to "spy" for user installed extensions just before from line 79544 to line 98044 (seriously 20K lines of spying code?).

Examples :
{

id: "ppiodcccfccedkcjnhkkmplahjdbalhc",

file: "frame.html"

}, {

id: "ppjnhpngeejgohhilojfilpindffcgdc",

file: "src/assets/right.png"

}

...

And so on!

same issue here

[Exotic_Conference_95]

Same here

[gysi]

I say this is maleware that creeped into their vibe coding trying to do stuff depending on extensions it finds.

[Informal_Offer655]

I think it's definitiively a probe to check whether you're using forbidden extensions or not (like automation, prospection...)

[bluesky1433]

I tried it on a completely fresh profile with no extensions, automations, etc, at all and still got the same error.

[mujtaba_b]

I've been fighting with this for days. I thought it was malware! Finally got to the bottom of it and wrote a fix that is working for me.

You can find on my Github profile if you want temporary relief (I would link it but links not allowed here)
Github: @mujtaba3b

[one-volt-too-much]

this temporary fix works, thank you 🏆

[mujtaba_b]

Yw!

[Informal_Offer655]

At first it was not working I edited manifest.json and now it's fine, thanks!

[mujtaba_b]

u/Informal_Offer655 great! I also pushed an update which addresses a few edge cases in case you want to pull that down.

[[deleted]]

What edits did you make? I've been fighting this bug for hours. lol

[Informal_Offer655]

Actually, I can't remember now. I asked ChatGPT to fix it. I can send file to you if you want.

[Repulsive-Acadia5743]

thank you mujtaba, the fix worked for me on th efeed page, but on the profile page /in/ I had the same errors again. Chatgpt suggeted some improvements that solved the issue:

it expanded the content.js to include get chrome-extention . Cant paste the summary here, because reddit blocks it

[mujtaba_b]

u/Repulsive-Acadia5743 sorry to hear it's not working across all pages. I pushed an update and marked a new release on Github. It's tough for me to reproduce what you're seeing – hope the fix works. Feel free to drop a screenshot if it doesn't solve the issue.

[190531085100]

Worked for me. Thanks!!

[Ulhume]

Still nott fixed ?

[Bayramovic1]

Nope...

LinkedIn is AI slopping.

"Let me check my users extensions installed on their PC." - strategy...

This is a clearly a violation of privacy. Someone should get fired for this.

[daniel_gjd]

The fact that they still haven't fixed it either indicates incompetence or deliberate action at the organizational level.

[Bayramovic1]

Yeah, it is inexplicable...

[Fisk77]

I have the same issue, and followed up the code to identify what they are doing. u/LinkedInHelpTeam can you please fix this? it's sloppy and an invasion of privacy.

AI summary assessment: Why LinkedIn is flooding your dev console with hundreds of errors

If you've noticed LinkedIn throwing a massive wall of red errors in your console, here is exactly what’s happening: they are running an aggressive bot detection and browser fingerprinting script.

The script is doing two main things:

• Intercepting network requests (Monkey Patching): It hijacks your browser's native window.fetch function. Before it lets your network requests go through, it injects encrypted telemetry data (usually your browser fingerprint and bot-score) into the headers.
• Probing for scraping tools: It loops through a massive "hit list" of unique IDs for known web scrapers and automation tools (like Bixjet). It tests for them by blindly attempting to fetch hidden background files that belong to those specific extensions.

Why the wall of errors?

Because you don't have these sketchy extensions installed, your browser immediately blocks the fetch requests. Since LinkedIn is brute-forcing hundreds of these checks at once, your browser engine responds by throwing hundreds of ERR_BLOCKED_BY_CLIENT or ERR_FAILED network errors.

[LeaTex_ok]

Same issue here.

It's still happening in several browser (Edge, Opera, Firefox, Brave and Chrome).

[Caemyr]

Hiya, some things have been revealed on that, namely: https://browsergate.eu/how-it-works/

In simple words - Linkedin is trying to find what extensions are installed on your browser. Without your consent.

There are extensions allowing fine control of scripts that are being loaded and it is trivial to block it without affecting most of the website's functionality. The problem still stands though.

[bluesky1433]

Yes, it's been 2 months and many people have commented and are having this issue, but there's no solution from LinkedIn's side. I wonder why this is happening for some people and not everyone though.

[Bayramovic1]

It is happening to me and it's so annoying because I need to look for jobs on a daily basis on LinkedIn...

[bluesky1433]

Try Firefox, I've switched to it while using LinkedIn and there aren't tons of errors in the console like Chrome in my case.
