LinkedIn reportedly detects 6,278 browser extensions and sends encrypted extension data with each request

LinkedIn is reported to scan users’ browsers for 6,278 installed extensions and encrypt the detected results into every request. The behavior suggests the platform may be using extension detection as part of its client-side telemetry or risk systems.

Scanning for installed extensions can strengthen fraud prevention, but it also raises privacy and fingerprinting concerns because extension lists can help identify users. The report reflects a broader trend of major platforms collecting richer browser signals to distinguish legitimate users from bots, often with limited visibility for end users.
