There are a couple of preferences associated with the Remote Agent:

Configurable preferences

Defines the remote protocols that are active. Available protocols are, WebDriver BiDi (1), and CDP (2). Multiple protocols can be activated at the same time by using bitwise or with the values. Defaults to 3 in Nightly builds, and 2 otherwise.


Limits the Remote Agent to be allowed to listen on loopback devices, e.g., localhost, and ::1.


Defines the verbosity of the internal logger. Available levels are, in descending order of severity, Trace, Debug, Config, Info, Warn, Error, and Fatal. Note that the value is treated case-sensitively.


Defines whether long log messages should be truncated. Defaults to true.
