A disputed browser scan by LinkedIn has triggered a public fight with a suspended extension developer and two lawsuits. At the center is whether the platform inspected users’ installed extensions and whether that inspection crossed a privacy line.

According to legal filings, the extension maker alleges that LinkedIn secretly probed users’ browsers to detect competing tools and then used that information to block or disadvantage them. The company behind the tool says its business collapsed after LinkedIn restricted its access and labeled it a threat.

LinkedIn rejects the accusations and frames the dispute as a straightforward enforcement issue. It says the extension was removed for automated data scraping that violated its terms, including large‑scale collection of profile information. The company also describes the lawsuits as based on fabricated claims designed to distract from that alleged scraping behavior.

The clash highlights long‑running tension between platforms and third‑party tools that tap public profiles and social graphs. It also raises questions about what platforms can examine inside a user’s browser in the name of security, and how much visibility users actually have into those checks.
