Comment (by ma1):

 This error message just mean that the window (as identified by tabId and
 frameId) which the message was sent to doesn't exist anymore.
 Due to the asynchronous nature of all the WebExtensions API this is hardly
 an exceptional case, and it's not something which needs to be cared for
 from a security standpoint, hence the best course for me is probably
 wrapping each of the two sendMessage() calls in its try/catch block and
 just make it quiet.
