Tor Messenger 0.5.0b1 is released

by sukhbir | September 28, 2017

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 XMPP, IRC, Twitter, and others; enables ​Off-the-Record (OTR) Messaging automatically; has an easy-to-use graphical user interface; and a secure automatic updater.

We are pleased to announce another public beta release of Tor Messenger that features important improvements to its stability and security. All users are encouraged to upgrade.

Mozilla ESR52

This release of Tor Messenger is based on Firefox ESR52, specifically tor-browser-52.3.0esr-7.0-1-build1 and THUNDERBIRD_52_3_0_RELEASE on comm-central.

Deterministic Builds

Tor Messenger builds are now reproducible for Windows and macOS as well; earlier, only Linux builds were reproducible (#10942). This means that anyone building Tor Messenger from source should end up with identical byte-for-byte binaries to the ones we release. To get started with building Tor Messenger (something we encourage!), please refer to the instructions in the file. Since this is a fairly involved process, talk to us on IRC or the comments section below if you need help.

XMPP Improvements

This version of Tor Messenger introduces temporary XMPP accounts (a feature inspired by ChatSecure) that creates an XMPP account automatically with a random username and password (#16606). This helps you to quickly set up an account and get a conversation started without requiring you to bother with the registration or account details. These accounts don't expire automatically but the intent is that you can use them as throwaway accounts and quickly create new ones when required. (Note: Currently, some data remains after deleting an account. See #23675)

Starting with this release, Tor Messenger will attempt to automatically use the onion service for known XMPP servers which helps improve the security of your connection (#13855). The current list includes onion addresses for,,, and We plan to add more servers in the subsequent releases. (Note: Existing accounts remain unchanged. This setting is only applied during new account setup.)

Other Notable Changes

Tor Messenger for Linux is now built with Selfrando for hardened builds (#22229). For more information on Selfrando, please refer to the Q and A with Georg.

This release also fixes the Tor Messenger crash on Windows XP that prevented it from starting (#17469).


Please note that Tor Messenger is still in beta. The purpose of this release is to help test the application and provide feedback. At-risk users should not depend on it for their privacy and safety.

Linux (32-bit)

Linux (64-bit)

Looking forward to your response.

Just wait for 0.3.2 tor for its new secure onion address, current onion address system is risky, those XMPP onion servers can be faked...

This release is really great!
Could you, please, release Tor Mail on the same base?

We (well, I should say "I" here since I can only speak for myself) have plans for working on Tor Mail at some point but I can't give you a timeline yet, not even an approximate one.

Hope you guys make it work asap, it has huge potential. XMPP account said "Connected for few seconds" does it mean that I was connected? This add new account/configuration window didn't disappear after user registration. Also no sign on the chat itself that I was using this exact client. Just reporting what I saw and I know that it is in beta, hope you guys make it work so we can all enjoy it! Cheers

"Connected for few seconds" means that you have been connected to the particular account and shows the time elapsed since the connection.

As far as your second issue, can you explain a bit more? When you tried registering for a new account, it will just show connected and then you will have to add the person you want to talk to and then start the chat.

Very interested in "beginning" to learn "open sourced" code and the initial beginnings of the tor scene. I am in my 70's and am fascinated by the algorithmic dexterity of you youngsters. Is there a secret place atop a cloud covered eerie bat infested cavern where those of us who still lagging behind, and missing all the fun...a place for "baby steps" to be had?
