General content anonymity caution note

Codename: TorBirdy

TorBirdy is Torbutton for Thunderbird, Icedove and related Mozilla mail clients. It may also work with other non-web browser Mozilla programs such as Sunbird.


TorBirdy is experimental. Use at your own risk! Please read our design goals document to understand what we're trying to accomplish with TorBirdy for our users.

General content anonymity caution note:

TorBirdy has known leaks in the Message-ID and in the Date header, we're working on merging an upstream patch that will allow these leaks to be closed. There are no known proxy leaks unless you use additional extensions that do not respect the proxy settings of Thunderbird. If you use GnuPG and Enigmail, we encourage you to use it with a local HTTP proxy due to the issues mentioned (see #2846) regarding GnuPG.

Install from Mozilla, the Tor Project website, or Github

TorBirdy 0.0.13 has passed Mozilla's preliminary review and is available from Mozilla Add-ons. TorBirdy is also available from the Tor Project website and from GitHub as a XPI.


Note: Use this chapter with care until TorBirdy developers remove this notice. User contributed, not from TorBirdy developers.

Additional Add-Ons

enigmail (OpenPGP GPG for Thunderbird)

(Source: #6019)

Please read #2846.

mixgui (mixminion remailer for Thunderbird)

(Source: #6020) MixMinion isn't really ready for prime time. While we'd love to hear feedback about use with TorBirdy, I'm skeptical that MixMinion itself works very well. So for now, I'd suggest that you do not mix that plugin and TorBirdy unless you've got some good data or good feedback.

Lightning (Calendar for Thunderbrid)

See #6319.
