Submitting patches

See the Firefox Contributors’ Quick Reference for how to write a patch and submit it for review. Don’t worry about which person to select for reviewing your code; for geckodriver it will be done automatically.

Once you have contributed a couple of patches, we are happy to sponsor you in levelling up. With commit access level 1 you will have permission to use the Firefox CI to trigger your own “try runs” to test your changes. You can use the following try preset to run the most relevant tests:

% ./mach try --preset geckodriver

This preset will schedule geckodriver-related tests on various platforms. You can reduce the number of tasks by filtering on platforms (e.g. linux) or build type (e.g. opt):

% ./mach try --preset geckodriver -xq "'linux 'opt"
