(Core :: DOM: Networking, defect, P5)

Description

[Alex]

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36

Steps to reproduce:

Open the console and enable persistent logging
Setup a http page which calls sendBeacon in an onbeforeunload event handler which posts to a http page ( eg http://jsfiddle.net/4gtcxny5/1/show/ )
Navigate the browser to a https page by typing in the URL


Actual results:

Saw a mixed content warning in the console:
POST http://fiddle.jshell.net/blah [Mixed Content][HTTP/1.1 404 NOT FOUND 115ms]


Expected results:

No mixed content warning

I can confirm that on the latest Nightly the following warning is received:
POST http://fiddle.jshell.net/blah [Mixed Content] [HTTP/1.1 404 NOT FOUND 283ms]

If this is still a problem it's a problem with the sendBeacon() code triggering the developer console (probably somewhere in the subsystem responsible for doing the request).

Christoph, is this something you can look at?

This Bug was filed 5 years ago and the Mixed Content Blocker changed quite drastically in between. I can't reproduce the bug, hence I'll just link that bug to the master bug for mixed content and will mark it as WORKSFORME.
