"Some parts of this page are not secure" ... except everything is served over HTTPS
Firefox shows this message: "Some parts of this page are not secure.."
Even on some pages where everything is secure!
For example, this image: https://www.parrotdomains.com/parrot_mascot.jpg
Chrome does not show any error or warning.
Do other people get the same issue?

Perhaps it's about a favicon.
Yeah, you could be right because the website doesn't seem to have a favicon.
No problems here with that page. I get a green padlock.
You can check the Web Console (Tools -> Web Developer) for messages about blocked content and about the presence of mixed or unsafe content.
You can check the Network Monitor for possible issues.
If necessary use "Ctrl+F5" or "Ctrl+Shift+R" (Mac: Command+Shift+R) to reload the page and bypass the cache to generate a fresh log.
