[tor-talk] Is Thunderbird safe to use with Tor now?

[Cypher]

Hey Everyone,

I have a an account on an anonymous mail service that I created via
Tor. I'd like to access this account via POP3/SMTP using Thunderbird.
According to the docs[1], Thunderbird is not safe to use with Tor.
This advice was from 2012. Have things changed? Is Thunderbird now
safe to use with Tor or still a bit shaky?

Thanks!
Cypher
