LinkedIn injects a 2.7MB JavaScript bundle that silently scans for 6,000+ Chrome extensions — including ones revealing religion, political orientation, and neurodivergence. Then fingerprints your hardware. No disclosure, no opt-out.
“LinkedIn injects a 2.7MB JavaScript bundle that silently scans for 6,000+ Chrome extensions — including ones revealing religion, political orientation, and neurodivergence. Then fingerprints your hardware. No disclosure, no opt-out.”
LinkedIn — owned by Microsoft — is injecting a 2.7-megabyte JavaScript bundle into your browser that silently scans for over 6,000 Chrome extensions. Not security extensions. Not ad blockers. Extensions that reveal your religion, political affiliation, mental health status, and whether you're secretly job hunting.
The scan detects extensions for prayer reminders (religion), political news filters (political orientation), ADHD tools and accessibility aids (neurodivergence), job search tools (employment status), and VPN extensions (privacy concerns). This isn't security — it's profiling.
In 2024, LinkedIn scanned for 461 extensions. By 2026, that number exploded to over 6,000 — a 1,252% increase. The expansion wasn't announced. There was no updated privacy policy. No user notification. They just started scanning for more and more of your personal information.
You cannot disable the scan. You cannot opt out. If you use LinkedIn, your browser is scanned. The JavaScript bundle loads automatically and runs silently. The only way to avoid it is to not use LinkedIn — which, for millions of professionals, isn't an option.
LinkedIn isn't a startup moving fast and breaking things. It's owned by Microsoft — one of the largest corporations on Earth. This scanning behavior was engineered, tested, and deployed by a company with thousands of lawyers. They knew exactly what they were doing.
