Introduces a new kind of target "main-process", which is not bound to any particular browser-element/browsing-context. This implements only a subtest of domains and typical won't support the "content" ones. This will require some more work in order to acknowledge having multiple kinds of targets. We will also have "worker", "addon" and remoted-frames which will be very similar to tabs. Depends on D22690 Differential Revision: https://phabricator.services.mozilla.com/D22691 --HG-- extra : moz-landing-system : lando
