Security finding
The page references files with a protocol-relative address
Security Info Severity: Low
Part of the audit Mixed content and insecure forms. Finding id: security.protocolRelativeResources.
What it costs you
Such an address copies the scheme of the page. On HTTPS that is harmless. If the page is ever opened over HTTP, the files load over HTTP too and can be changed on the way.
What to do
Write https:// in front of these addresses.
What it checks
- File loaded without a fixed HTTPS address
How to fix it
Write the scheme out
- Search the templates for src="// and href="// and put https: in front.
How to check: View the page source: no src or href starts with //.
