As such it should hit the following code in driver.js: https://dxr.mozilla.org/mozilla-central/rev/13a2e506992ccf07c1358d9f22cbf2dfdcb0120f/testing/marionette/driver.js#1533-1548 So we most likely wait for the `browserListening` promise to be resolved: https://dxr.mozilla.org/mozilla-central/rev/13a2e506992ccf07c1358d9f22cbf2dfdcb0120f/testing/marionette/driver.js#624-635 Maybe my changes for bug 1332122 sometimes can cause this issue. I don't see a reason right now to dig deeper into this given the very low intermittent failure rate.
