Preferences
There are a couple of preferences associated with the Gecko remote protocol:
marionette.enabled
Starts and stops the Marionette server. This will cause a TCP
server to bind to the port defined by marionette.port.
If Gecko has not been started with the -marionette flag or the
MOZ_MARIONETTE environment variable, changing this preference
will have no effect. For Marionette to be enabled, either one of
these options must be given to Firefox or Fennec for Marionette
to start.
marionette.debugging.clicktostart
Delay server startup until a modal dialogue has been clicked to allow time for user to set breakpoints in the Browser Toolbox.
marionette.log.level
Sets the verbosity level of the Marionette logger repository. Note that this preference does not control the verbosity of other loggers used in Firefox or Fennec.
The available levels are, in descending order of severity, Trace,
debug, config, info, warn, error, and fatal. The value
is treated case-insensitively.
marionette.log.truncate
Certain log messages that are known to be long, such as wire protocol dumps, are truncated. This preference causes them not to be truncated.
marionette.port
Defines the port on which the Marionette server will listen. Defaults to port 2828.
This can be set to 0 to have the system atomically allocate a free port, which can be useful when running multiple Marionette servers on the same system. The effective port is written to the user preference file when the server has started and is also logged to stdout.
marionette.prefs.recommended
By default Marionette attempts to set a range of preferences deemed suitable in automation when it starts. These include the likes of disabling auto-updates, Telemetry, and first-run UX.
The user preference file takes presedence over the recommended preferences, meaning any user-defined preference value will not be overridden.
marionette.contentListener
Used internally in Marionette for determining whether content scripts can safely be reused. Should not be tweaked manually.
This preference is scheduled for removal.
