Marionette, the next generation of FirefoxDriver Marionetteis nothing but the next generation of FirefoxDriver, i.e. Automation driver for Mozilla’s Gecko engine. It can remotely control either the UI or the internal JavaScript of a Gecko platform, such as Firefox – giving it a high level of control and ability to replicate user actions.
