# WebDriver (HTTP / BiDi)
# ==============================================================
#
# WebDriver is a remote control interface that enables introspection and
# control of user agents. It provides a platform- and language-neutral wire
# protocol as a way for out-of-process programs to remotely instruct the
# behavior of web browsers.
#
# The Gecko implementation is backed by Marionette and Remote Agent.
# Both protocols are not really toolkit features, as much as Gecko engine
# features. But they are enabled based on the toolkit, so here it lives.
#
# Marionette remote protocol
# -----------------------------------------------------------
#
# Marionette is the Gecko remote protocol used for various remote control,
# automation, and testing purposes throughout Gecko-based applications like
# Firefox, Thunderbird, and any mobile browser built upon GeckoView.
#
# It also backs ../testing/geckodriver, which is Mozilla's WebDriver
# implementation.
#
# The source of Marionette lives in ../remote/marionette.
#
# For more information, see:
# https://firefox-source-docs.mozilla.org/testing/marionette/index.html
#
# Remote Agent (WebDriver BiDi / partial CDP)
# -----------------------------------------------------------
#
# The primary purpose is the implementation of the WebDriver BiDi specification.
# But it also complements the existing Firefox Developer Tools Remote Debugging
# Protocol (RDP) by implementing a subset of the Chrome DevTools Protocol (CDP).
#
# The source of Remote Agent lives in ../remote.
#
# For more information, see:
# https://firefox-source-docs.mozilla.org/remote/index.html
