Steps to reproduce:

1- Open the Firefox
2- Go this website :

Actual results:

Although a web page icon loads as http, it may appear secure.

Expected results:

Please look at the's source code. You can see favicon icon as https. But if you open favicon file, it' redirecting to http page. This means : favicon file loading as http. This means : web page is not secure. But Firefox show web page as secure

proof of concept:

How can i help you ?
We don't actually have a mixed content indicator. I'm not sure what we should do with this bug.

Because of WKWebView we are a bit limited here, but it does have a property that can tell us if the loaded page has mixed content I think.

Dan do you think there is something actionable here? We could turn this into a feature card on our trello board but that means we will need some guidance on the UX side of things.

"A Boolean value indicating whether all resources on the page have been loaded through securely encrypted connections."

I think this would be nice to expose in some way.
Marking as tracking-fxios so that it will show up in bug triage.
I want to learn situation.

Since we allow the load of mixed "passive" content anyway we're not protecting users from any of the privacy downsides. The indication is a warning to users, but more of a nudge for the site's authors to fix things. We don't need to keep this hidden.

If we're not showing a mixed-content indicator at all that's a bigger deal than just getting the favicon wrong.
