Since bug 1320233, a [Learn More] link is added in the Network Panel.

The link is added only next to the whitelisted HTTP Header. The comparison with these entries seems to be case-sensitive.

A [Learn More] link is not added next to Etag (Canonical case: ETag), x-xss-protection (Canonical case: X-XSS-Protection), or x-frame-options (canonical case: X-Frame-Options).

HTTP headers are not case sensistive, so we should be more lenient.
I've added a link to https://irccloud.mozilla.com/ where these 3 specifics headers are not using the canonical case.
I can look into this. I'll have a patch ready by the end of today.
Thanks Eduardo!

A day late, but here's the patch. This makes the header lookup case-insensitive.

You don't have to iterate the entire array if you find first match so, it's better to use: Array.find()
