Private Relay provides generated email addresses to use in place of personal email addresses.

Recipients will still receive emails, but Private Relay keeps their personal email address from being harvested, and then bought, sold, traded, or combined with other data to personally identify, track, and/or target them.

• python 3.7 (suggest using virtualenv)
• SocketLabs Server

1. Clone and change to the directory:

   git clone [email protected]:mozilla/fx-private-relay.git
   cd fx-private-relay

2. Create and activate a virtual environment:

   virtualenv env
   source env/bin/activate

3. Install requirements:

   pip install -r requirements.txt

4. Copy .env file for decouple config:

   cp .env-dist .env

5. Add a SECRET_KEY value to .env:

   SECRET_KEY=secret-key-should-be-different-for-every-install

6. Migrate DB:

   python manage.py migrate

7. Create superuser:

   python manage.py createsuperuser

8. Run it:

   python manage.py runserver

Next you'll need to enable Firefox Accounts auth ...

To enable Firefox Accounts authentication on your local server, you can use the "private-relay (local)" OAuth app on oauth-stable.dev.lcip.org.

To do so:

1. Set ADMIN_ENABLED=True in your .env file

2. Go to the django admin page to change the default site.

3. Change example.com to 127.0.0.1:8000 and click Save.

4. Go to the django-allauth social app admin page, sign in with the superuser account you created above, and add a social app for Firefox Accounts:

   • Provider: Firefox Accounts
   • Name: oauth-stable.dev.lcip.org
   • Client id: 7477974d5019bdaf
   • Secret key: ping groovecoder for this
   • Sites: 127.0.0.1:8000 -> Chosen sites

Now you can sign into http://127.0.0.1:8000/ with an FxA. Remember: you'll need to use an account on oauth-stable.dev.lcip.org, not the production accounts.firefox.com.

If you want to enable SocketLabs Inbound API to deliver email messages to your local server, you will need a domain where you can set MX records, and something like ngrok to forward public URLs to your local server.

1. In your DNS, add an MX record

   • Priority: 10
   • Value: mx.socketlabs.com

2. In your SocketLabs account, add a new server. ("Free" includes 500 messages per month.)

3. Under "Injection API", copy the Injection API Key into your SOCKETLABS_API_KEY env var

4. Under "For Developers", choose "Inbound API", and enable Inbound Parsing.

5. Copy the Secret Key into your SOCKETLABS_SECRET_KEY env var

6. Copy the Validation Key into your SOCKETLABS_VALIDATION_KEY env var

7. Restart your runserver process

8. With your server running on 127.0.0.1:8000, use ngrok to forward a public domain to it:

   • ngrok http 127.0.0.1:8000
     • You should see output like Forwarding https://bec216e2.ngrok.io -> http://127.0.0.1:8000

9. On the Inbound API screen, set the Endpoint URL to your ngrok domain, followed by /emails/inbound (e.g., https://bec216e2.ngrok.io/emails/inbound), and click "Validate".

   • It should say "Your Endpoint URL is valid"

10. At the "Add Address/Domains" prompt, enter your domain where you set the MX records.

    • @domain should show up under "Current Entries"

11. Click "Update"

12. Test sending an email to test@domain

    • You should see SocketLabs send the request to your local runserver process thru your public ngrok URL.

The add-on adds Firefox UI to generate and auto-fill email addresses. You may want to build the add-on so that it communicates with your 127.0.0.1:8000 server instead of the production relay.firefox.com server:

1. In the extension/ directory, run npm install and then npm run build

2. Use about:debugging to install the resulting static/downloads/addon/latest/private_relay.zip file.

   • Note: A link to the .zip is also available at http://127.0.0.1:8000/accounts/profile/

In addition to the requirements for dev, production environments should use:

• PostgreSQL-compatible DB

Production environments should also set some additional environment variables:

DATABASE_URL=postgresql://<username>:<password>@<host>:<port>/<database>
DJANGO_SECURE_HSTS_SECONDS=15768000
DJANGO_SECURE_SSL_REDIRECT=True
