Remote Protocols
================

Firefox supports several remote protocols, which allow to inspect and control
the browser, usually for automation purposes:

* :ref:`marionette-header`

* :ref:`remote-protocol-cdp-header`

* :ref:`webdriver-bidi-header`


Common documentation
====================

The following documentation pages apply to all remote protocols

.. toctree::
  :maxdepth: 1

  Building.md
  Debugging.md
  Prefs.md
  Testing.md
  CodeStyle.md
  Security.md


.. _marionette-header:

Marionette
==========

Marionette is used both by internal tools and testing solutions, but also by
geckodriver to implement the `WebDriver (HTTP) specification`_. The documentation
for Marionette can be found under `testing/marionette`_.

.. _WebDriver (HTTP) specification: https://w3c.github.io/webdriver/
.. _testing/marionette: /testing/marionette


.. _remote-protocol-cdp-header:

Remote Protocol (CDP)
=====================

Firefox implements a subset of the `Chrome DevTools Protocol`_ (CDP) in order to
support third party automation tools such as `puppeteer`. The documentation for
the remote protocol (CDP) implement can be found at `remote/cdp`_.

.. _Chrome DevTools Protocol: https://chromedevtools.github.io/devtools-protocol/
.. _remote/cdp: cdp/


.. _webdriver-bidi-header:

WebDriver BiDi
==============

`The WebDriver BiDi specification <https://w3c.github.io/webdriver-bidi>`_
extends WebDriver HTTP to add bidirectional communication. Dedicated
documentation will be added as the Firefox implementation makes progress.
