this.messageManager.sendAsyncMessage("Extension:CloseProxyContext", {childId: this.id});

does not match

Services.mm.addMessageListener("API:CloseProxyContext", this, true);

And in an OOP world, the parent process should have minimal assumptions on the child process, in order to provide a better security. In this case, we should also dispose the proxy context if the child process terminates.
> we should also dispose the proxy context if the child process terminates.

This is already handled by subscribing to message-manager-close and disposing its associated ProxyContexts.

The patch is easy, s/Extension:/API:/.
How can I add a regression test for this bug?

The only way I can think of where this might go wrong is if a content script used storage.local.onChanged.addListener. When the content page navigates, we could try to see if the listener fires after that.

promiseOneMessage might be a better name given how we've done stuff like this in the past.

Tests were failing because Android does not support the tabs API. I disabled the test for Android, rebased the patch and verified locally that no test failures are generated on Fennec. Please land it again.
