The following permissions are needed for Header-Editor to run:

webRequest - Used to access the requests being sent out.

Note: Response headers do not appear in the Network Inspector, however they are supplied to your code. For more details, see:

This how to view response headers: var req = new XMLHttpRequest(); req.open('GET', document.location, false); req.send(null); var headers = req.getAllResponseHeaders().toLowerCase(); alert(headers);
