The difference between geckodriver and puppet

Question

I do not quite understand the difference between geckodriver and marionette .

• Can anyone clarify the difference between the two?

For example, when I use Selenium WebDriver to control the Firefox browser, I need a geckodriver binary to listen to

Answer 1

Selenium uses the W3C Webdriver protocol to send requests to Geckodriver, which translates them, and uses the Marionette protocol to send them to Firefox

Selenium <- (W3C Webdriver) → Geckodriver <--- (Marionette) ---> Firefox
