Since Brave uses Tor control channel, it is no longer possible for websites or extensions to connect to the Tor socks proxy. This may be a good thing for security, but some extensions may need to connect to the Tor proxy in order to make legit and hidden requests. This would increase privacy when extensions are doing requests in Tor mode.
So I propose two solutions to this
Proposal 1, Exposing Tor proxy address
Proposal 2, Route all extension traffic through Tor
This one would be harder to develop. Route all traffic through Tor, transparently, but it would cause some technical issues if the endpoint doesn’t accept Tor. Also, if the extension includes some metadata in its requests this could harm privacy. But maybe we can solve those issues by making the routing opt-in in the extensions page.
Proposal 3, Bring back fixed port for Tor as an option #12424
This one is just reverting to the previous behaviour, but it will cause security issues, right?
