User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:46.0) Gecko/20100101 Firefox/46.0
Build ID: 20160425115337
Steps to reproduce:
Return {cancel: true} from an `onBeforeSendHeaders` listener in Firefox 46 on Ubuntu 14.04.
Actual results:
Throws
NS_ERROR_XPC_NOT_ENOUGH_ARGS: Not enough arguments [nsIHttpChannel.cancel] WebRequest.jsm:366:0
and the load continues.
Expected results:
The load should have been terminated without error.
The attached WebExtension demonstrates the problem. It blocks odd-numbered Bugzilla bug reports in `onBeforeRequest`, and all even-numbered reports in `onBeforeSendHeaders`. Each listener reports whether it blocked or passed each report URL. In Chrome, all reports are blocked. In Firefox, only odd reports are blocked.

I think this was fixed by bug 1163862. Please reopen if you can reproduce on Firefox 47 or newer.
