DUPLICATE: previously had wrong subject; external messaging extension question

Hi



I'm looking for Webextensions help.





I have a Webextension which launches a native app using

the chrome.runtime.sendNativeMessage(...) API.



This extension normally invokes an already running process to get some

work done; noramlly the end result is to download a document from a

server and start a Microsoft Office Application (e.g. WinWord.exe) to

edit/review.



The extension returns immediately.



However, there is a problem. If the long-running application is not

actually running, then it is started. But when the extension gets a

response message, it kills the native application, and every process

created by it.



This is unexpected (by me); Chrome behavior differs.



Is this expected behavior by you? Is it documented? Is there a

mechanism for my native application to launch a task which continues

to run after the native application has returned to Firefox, and

exited?
