1202478 - Run WebExtension callbacks asynchronously

Status: RESOLVED FIXED

(WebExtensions :: Untriaged, defect)

Description

[Bill McCloskey [inactive unless it's an emergency] (:billm)]

Attachment: patch

Even though the API is asynchronous, callbacks are run synchronously right now. That seems to cause problems for Adblock Plus. This patch just runs most callbacks asynchronously. The exception is webRequest, since we need to know the blocking decision right away. Eventually that will need to be fixed before implementing out-of-process WebExtensions.

Backed out the whole push in https://hg.mozilla.org/integration/mozilla-inbound/rev/f2e83a8b6b8e since it was intertangled and I wasn't entirely sure which part caused Mulet mochitest-5 to become permaorange with https://treeherder.mozilla.org/logviewer.html#?job_id=14545777&repo=mozilla-inbound
