Attachment: Screenshot of bug

While investigating Bug 840656 I noticed that "Inspect network request" window doesn't show response from server if response contains multiple "Access-Control-Allow-Origin" headers. However, Wireshark can show it, see Bug 840656 comment 2
STR:
1) Open web console
2) Open http://riotpixels.com/
3) Click on GET link

Expected result:
Request and response are shown

Actual result:
Only request is shown (see attachment)

Thank you for the bug report!

riotpixels.com seems to work now. Do you have a test case page where we can see the issue you are describing?

Patch in Bug 814117 contains testcase for multiple Access-Control-Allow-Origin headers.

Thank you. I was able to confirm the bug after a bit of fighting with apache which insisted to merge multiple headers with the same name (multiple values become comma separated).

It seems this is a corner-case bug, IIANM.
