Is JabRef Browser Extension safe?

Clean risk

JabRef Browser Extension sends page reference details to a local JabRef app when you trigger an export.

When you open the extension popup or page action, it uses the active tab title and URL, and on supported pages it can extract reference items from the page. It sends the resulting BibTeX or reference data to a local JabRef HTTP endpoint, falling back to the JabRef native messaging host if that local endpoint is unavailable.
