To enable Marionette on Firefox for Android, the most reliable method is to use Firefox Beta or Nightly, as these versions allow access to about:config. You can manually create the marionette.enabled preference as a boolean and set it to true. This should enable Marionette for those builds. However, due to the Firefox/Geckoview divide, there may still be some limitations or issues on Android.
If you are using a debug build (such as Fennec), Marionette is enabled by default, and you can run tests locally on an emulator or device. For non-debug builds, enabling Marionette typically requires passing the --marionette flag when starting Firefox, but this is not always possible on standard Android releases.
In summary:
Use Firefox Beta or Nightly.
Go to about:config and manually add marionette.enabled as a boolean, set to true.
For debug builds, Marionette is already enabled.
