Tor Messenger Beta: Chat over Tor, Easily
As of March 2018, Tor Messenger is no longer maintained and you should NOT use it. Please see the announcement for more information.
Today we are releasing a new, beta version of Tor Messenger, based on Instantbird, an instant messaging client developed in the Mozilla community.
What is it?
Tor Messenger is a cross-platform chat program that aims to be secure by default and sends all of its traffic over Tor. It supports a wide variety of transport networks, including Jabber (XMPP), IRC, Google Talk, Facebook Chat, Twitter, Yahoo, and others; enables Off-the-Record (OTR) Messaging automatically; and has an easy-to-use graphical user interface localized into multiple languages.
What it isn't...
Tor Messenger builds on the networks you are familiar with, so that you can continue communicating in a way your contacts are willing and able to do. This has traditionally been in a client-server model, meaning that your metadata (specifically the relationships between contacts) can be logged by the server. However, your route to the server will be hidden because you are communicating over Tor.
Today we are releasing a beta version with which we hope to gain both usability and security related feedback. There have been three previous alpha releases to the mailing lists that have already helped smooth out some of the rougher edges.
- On Linux, extract the bundle(s) and then run:
- On OS X, copy the Tor Messenger application from the disk image to your local disk before running it.
- Note that as a policy, unencrypted one-to-one conversations are not allowed and your messages will not be transmitted if the person you are talking with does not have an OTR-enabled client. You can disable this option in the preferences to allow unencrypted communication but doing so is not recommended.
On all platforms, Tor Messenger sets the profile folder for Firefox/Instantbird to the installation directory.
We are doing automated builds of Tor Messenger for all platforms.
The Linux builds are reproducible: anyone who builds Tor Messenger for Linux should have byte-for-byte identical binaries compared with other builds from a given source. You can build it yourself and let us know if you encounter any problems or cannot match our build. The Windows and OS X builds are not completely reproducible yet but we are working on it.
What's to Come
Our current focus is security, robustness and user experience. We will be fixing bugs and releasing updates as appropriate, and in the future, we plan on pairing releases with Mozilla's Extended Support Release (ESR) cycle. We have some ideas on where to take Tor Messenger but we would like to hear what you have to say. Some possibilities include:
- Reproducible builds for Windows and OS X
- Automatic updates
- Improved Tor support
- OTR over Twitter DMs
- Produce (and distribute) internationalized builds
- Secure multi-party communication (np1sec)
- Encrypted file-transfers
- Usability study
How To Help
Give it a try and provide feedback, requests, and file bugs (choose the "Tor Messenger" component). If you are a developer, help us close all our tickets or help us review our design doc. As always, we are idling on IRC in #tor-dev (OFTC) (nicks: arlolra; boklm; sukhe) and subscribed to the tor-talk/dev mailing lists.
Please note that this release is for users who would like to help us with testing the product but at the same time who also understand the risks involved in using beta software.
Thanks and we hope you enjoy Tor Messenger!
Update: For Windows 10 (and some Windows 7, 8) users who were experiencing an issue in Tor Messenger where it wouldn't start, we have updated the download links above with a newer version that fixes the problem described in bug 17453.
Very gratifying to see how much interest there is in TM. If we can get TM in Tails it could be very helpful for whistleblowers, human rights workers, cybersecurity researchers, reporters, medical practitioners, telecom engineeers, climate scientists, political dissidents, and other endangered people.
Could TM become the killer app that makes Tor usage mainstream?
