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.
We are also excited about systems like Pond and Ricochet, which try to solve this problem, and would encourage you to look at their designs and use them too.
- 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.
