Thanks you for this plugin: I added a custom authorization header in my browser to login without going to the login page to enter email and password

Very useful extension. Note: I need to change the Host: header to test a cloudfront setup before going live. That did not work in chrome, but it works with this same extension on Firefox. I suspect Chrome changed a setting that prohibits messing with the Host header ?
