Is Transmitter for Transmission safe?

Low risk

Transmitter for Transmission lets any website ask the extension to add a torrent to the configured server.

The extension registers a special transmitter.web-extension URL handler for adding magnet links and torrent URLs. A web page can request that URL to trigger the extension's privileged add-torrent flow, which sends the torrent-add command to the user's configured Transmission RPC server.
