Dear resolver, please explain why Firefox resolves magnet protocol to torrent client while tor browser can't. about:config on Firefox has no entry for magnet keyword but it resolves magnet protocol URIs to client automatically without any issue. On the other hand latest tor browser does not resolve magnet protocol uri without manually copying it to the client application by hand. about:config network.protocol-handler.expose.magnet false setting described below does NOT resolved problem either. I am using the latest tor browser and firefox on windows 10 pro. Please explain us succinctly well the difference how Firefox behaves on magnet protocol URI resolving and how to resolve magnet URI successfully in Tor Browser just like Firefox does. Tor browser refers to Mozilla on it's bug tracker if I am not mistaken. Thank you for your help on this particular issue.
