## Before using TorBirdy
|
|
|
The preferences TorBirdy changes are documented [here](./torbirdy/changes).
|
|
|
|
|
|
When you install TorBirdy, it modifies and adds many preferences to configure Thunderbird to be used securely over the Tor network.
|
|
|
|
|
|
TorBirdy enforces the preferences it sets and attempts to change them using Thunderbird's settings or the configuration editor will not work as all such changes will be discarded when Thunderbird restarts. This is because we believe that these preferences should ''not be changed'' -- whether deliberately; by mistake; or due to another extension -- as doing so can compromise your anonymity. There are however some preferences that can be changed and they can be accessed through TorBirdy's [wiki:torbirdy/preferences preferences] dialog. Please note that if you are not an advanced user, you should '''NOT''' change any setting unless you are very sure of what you are doing.

|
|
|
|
|
|
The preferences that TorBirdy changes are restored to their original values when it is uninstalled or disabled, thus restoring your Thunderbird's state to exactly what it was prior to TorBirdy's installation. If you find that TorBirdy leaves evidence of its installation in any way, please file a bug report.

## Required Software
|
|
|
|
|
|
This short guide should help you to set up your Thunderbird email client to send and fetch email via Tor. It can be used for both new and existing email accounts in Thunderbird.
|
|
|
|
|
|
Please bear in mind that email accounts that have been used without Tor before offer '''less''' privacy/anonymity/weaker pseudonyms than email accounts that have always been accessed with Tor. But nevertheless, TorBirdy is still useful for existing accounts or real-name email addresses. For example, if you are looking for location anonymity -- you travel a lot and don't want to disclose all your locations by sending emails -- TorBirdy works wonderfully!

1. Install Tor:

|
* On Windows and OS X, download and install the [https://www.torproject.org/download/download-easy.html.en Tor Browser Bundle]. When you want to use TorBirdy, you have to start the Bundle (if it is not already running.)

|
|
* On Unix, Linux and BSD you should use your distributor's packages, or if available, the ones [https://www.torproject.org/download/download-unix.html.en provided by the torproject]. You can of course also use the Tor Browser Bundle.

## Installing TorBirdy in Debian
|
|
|
TorBirdy is in Debian starting version 0.1.2 (package: xul-ext-torbirdy). To install TorBirdy (probably not the latest version, so you probably do not want to do this) in Debian:
|
|
|
|
|
|
{{{
|
|
|
```
|
|
|
apt-get install xul-ext-torbirdy
|
|
|
}}}

|
|
== Troubleshooting ==
|
|
|
```
|
|
|
## Troubleshooting
|
|
|
If things don't work for you:
|
|
|
|
|
|
1. Make sure Tor is running and listening on `127.0.0.1` (`localhost`) on port `9150`.
|
|
|
* If you are using standalone Tor (and ''not'' Tor Browser), you most likely have Tor running on `9050` (the Tor default). In that case, go to "Use custom proxy settings" in TorBirdy's settings and change the port to `9050`. Then click on "Test Proxy Settings" to confirm. The check page should say "Congratulations. This browser is configured to use Tor."

=== How do I send and receive HTML emails? ===
|
|
|
### How do I send and receive HTML emails?
|
|
|
HTML email is disabled both for sending and receiving mail. This is because HTML emails are unsafe and can compromise your identity; emails you send will be in plain text and HTML emails you receive will be sanitized and converted to plain text. You cannot change this behavior. (And you should not be sending HTML emails anyways!)

|
|
=== I noticed that the time information on sent messages is incorrect. Why is that? ===
|
|
|
### I noticed that the time information on sent messages is incorrect. Why is that?
|
|
|
When sending messages, TorBirdy sanitizes the date header and converts it to UTC to prevent local timestamp disclosure.
|
|
|
|
|
|
=== Why is Thunderbird not checking for new messages automatically? ===
|
|
|
TorBirdy prevents Thunderbird from automatically checking for new messages at startup and after a fixed time interval (usually ten minutes). Please see the [wiki:torbirdy/preferences#a-Selectlastaccessedmailfolderonstartup preferences] page for more information.

|
|
|
### Should I use POP or IMAP?
|
|
|
TorBirdy works with SMTP and IMAP/POP3 but POP3 is recommended over IMAP because POP3 is a much simpler protocol and less likely to have or introduce any new sketchy features.

== TorBirdy with Gmail ==
|
|
|
## TorBirdy with Gmail
|
|
|
TorBirdy works fine with Gmail and there should be no issues except in rare cases where certain exit nodes cause Gmail to lock an account (and therefore POP/IMAP access) until the user logs in through the web interface and enters a CAPTCHA.
|
|
|
|
|
|
Note (sukhe): Gmail does not work for all users and we don't know the blocking pattern. For example, on one Gmail account, there is no issue at all but on the other, it's almost impossible to log in over Tor no matter what I whitelist. And unfortunately, there isn't much we can do about this other than to switch to a Tor-friendly email provider.

## Security Requirements

|
### Proxy Obedience
|
|
|
All other content in Thunderbird obeys the SOCKS proxy.
|
|
|
|
|
|
=== Disk Avoidance ===
|
|
|
### Disk Avoidance
|
|
|
TorBirdy does not leave any trace of its installation. Caching is also disabled.

|
=== Location Neutrality ===
|
|
|
### Location Neutrality
|
|
|

|
|
### Anonymity Set Preservation
|
|
|
No information about the user-agent or locale is leaked.

|
==== Keyserver Operations ====
|
|
|
#### Keyserver Operations
|
|
|
|
|
|
Since 0.2.4, TorBirdy supports the `use-tor` mode in GnuPG and assumes you have the following settings configured for the keyserver lookups to work:
|
|
|
|
|
|
* In your `~/.gnupg/dirmngr.conf`, add the following line: `use-tor`.
|
|
|
* Assuming you have Tor running (daemon or Tor Browser), keyserver lookups should work. If not, try restarting `dirmngr` and try again.
|
|
|
|
|
|
See the [https://www.gnupg.org/documentation/manuals/gnupg/Dirmngr-Options.html GnuPG manual] for more information about the `use-tor` setting.

### Other Add-Ons
|
|
|
Please do not install random add-ons. If they have not been reviewed by the TorBirdy developers, they can harm your anonymity.
|
|
|
|
|
|
In the past we have offered to help audit add-ons (other than the ones we support) to ensure their compatibility with TorBirdy. Unfortunately, this takes time and effort and we are discontinuing auditing add-ons requested by users. We recommend that if you depend on TorBirdy for privacy that you do not install random add-ons, and if you really have to use them with Thunderbird that you do so in a different profile.

Translations are handled through two files: [torbirdy.dtd](https://gitweb.torproject.org/torbirdy.git/blob/HEAD:/chrome/locale/en/torbirdy.dtd) and [torbirdy.properties](https://gitweb.torproject.org/torbirdy.git/blob/HEAD:/chrome/locale/en/torbirdy.properties). The recommended way of submitting translations is through [Transifex](https://transifex.com). You will need to create an account and submit your translations for both [torbirdy.dtd](https://www.transifex.com/projects/p/torproject/resource/3-torbirdy-torbirdy-dtd/) and [torbirdy.properties](https://www.transifex.com/projects/p/torproject/resource/3-torbirdy-torbirdy-properties/). If you do not want to use Transifex, you can send us a pull request.
