7. Comments

	1. General Results, most used to calculate the result
A	name "relay.firefox.com" is subdomain, public suffix is ".com", top-level-domain is ".com", top-level-domain-type is "generic", tld-manager is "VeriSign Global Registry Services", num .com-domains preloaded: 89449 (complete: 231048)
A	Good: All ip addresses are public addresses
	Warning: Only one ip address found: relay.firefox.com has only one ip address.
	Warning: No ipv6 address found. Ipv6 is the future with a lot of new features. So every domain name should have an ipv6 address. See https://en.wikipedia.org/wiki/IPv6: relay.firefox.com has no ipv6 address.
A	Good: No asked Authoritative Name Server had a timeout
A	DNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
A	Good: destination is https
A	Good - only one version with Http-Status 200
A	Good: one preferred version: non-www is preferred
A	Good: No cookie sent via http.
	HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.
A	Good: All urls with http status 200/404 have a complete Content-Type header (MediaType / MediaSubType + correct charset)
A	http://relay.firefox.com/ 130.211.19.131	302	https://relay.firefox.com/	Correct redirect http - https with the same domain name
M	https://130.211.19.131/ 130.211.19.131	404		Misconfiguration - main pages should never send http status 400 - 499
N	https://130.211.19.131/ 130.211.19.131	404		Error - Certificate isn't trusted, RemoteCertificateNameMismatch
	Info: Checking all ip addresses of that domain without sending the hostname only one certificate found. Checking all ip addresses and sending the hostname only one certificate found. Both certificates are the same. So that domain doesn't require Server Name Indication (SNI), it's the primary certificate of that set of ip addresses.: Domain relay.firefox.com, 1 ip addresses, 1 different http results.
B	No _mta-sts TXT record found (mta-sts: Mail Transfer Agent Strict Transport Security - see RFC 8461). Read the result of server-daten.de (Url-Checks, Comments, Connections and DomainServiceRecords) to see a complete definition. Domainname: _mta-sts.relay.firefox.com

A				Good: default-src directive only with 'none' or 'self', additional sources are blocked.
A				Good: default-src without 'unsafe-inline' or 'unsave-eval'.
E				Bad: No form-action directive found. Use one to limit the form - action - destinations. form-action is a navigation-directive, so default-src isn't used.
E				Bad: No frame-ancestors directive found. Use one to limit the pages allowed to use this page in frame / iframe / object / embed / applet. frame-ancestors is a navigation-directive, so default-src isn't used.
E				Bad: No base-uri directive found. Use one to limit the URLs which can be used in a document's <base> element. Because it's a document directive, default-src isn't used, so an own directive is required.
A				Good: object-src only with 'none' or 'self' found, no scheme, no other urls. That blocks object / embed / applet - elements.
A				Good: script-src without 'unsafe-inline' and 'unsafe-eval' found. That's the recommended configuration.
A				Good: script-src without * and a scheme found.
A				Good: script-src without data: schema found. Why is this important? The data: schema allows hidden code injection. Insert <script src='data:application/javascript;base64,YWxlcnQoJ1hTUycpOw=='></script> in your page and see what happens.
A				Good: frame-src without data: defined or frame-src missing and the default-src used as fallback not allows the data: schema. That blocks hidden code injection. Insert <iframe src="data:text/html;charset=utf-8;base64,PCFET0NUWVBFIGh0bWw+PGh0bWw+PGJvZHk+PHA+YmVmb3JlPHNjcmlwdCB0eXBlPSJ0ZXh0L2phdmFzY3JpcHQiPmFsZXJ0KCdYU1MnKTwvc2NyaXB0PjxwPmFmdGVyPC9ib2R5PjwvaHRtbD4="></iframe> in your page and see what happens.

	4. Content- and Performance-critical Checks
A	Good: All checks /.well-known/acme-challenge/random-filename without redirects answer with the expected http status 404 - Not Found. Creating a Letsencrypt certificate via http-01 challenge should work. If it doesn't work: Check your vHost configuration (apachectl -S, httpd -S, nginx -T). Every combination of port and ServerName / ServerAlias (Apache) or Server (Nginx) must be unique. Merge duplicated entries in one vHost. If you use an IIS, extensionless files must be allowed in the /.well-known/acme-challenge subdirectory. Create a web.config in that directory. Content: <configuration><system.webServer><staticContent><mimeMap fileExtension="." mimeType="text/plain" /></staticContent></system.webServer></configuration>. If you have a redirect http ⇒ https, that's ok, Letsencrypt follows such redirects to port 80 / 443 (same or other server). There must be a certificate. But the certificate may be expired, self signed or with a not matching domain name. Checking the validation file Letsencrypt ignores such certificate errors. Trouble creating a certificate? Use https://community.letsencrypt.org/ to ask.
A	Good: Every https result with status 200 and greater 1024 Bytes is compressed (gzip, deflate, br checked).
A	Good: No https + http status 200 with inline CSS / JavaScript found
A	Good: Every https result with status 200 has a minified Html-Content with a quota lower then 110 %.
A	Good: Every https connection via port 443 supports the http/2 protocol via ALPN.
A	Good: All script Elements (type text/javascript) and src-Attribute have a defer / async - Attribute. So loading and executing these JavaScripts doesn't block parsing and rendering the Html-Output.
A	Good: All CSS / JavaScript files are sent compressed (gzip, deflate, br checked). That reduces the content of the files. 17 external CSS / JavaScript files found
	Warning: CSS / JavaScript files with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 0 external CSS / JavaScript files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 17 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 17 complete.
	Warning: Images with a missing or too short Cache-Control header found. Browsers should cache and re-use these files. 0 image files without Cache-Control-Header, 0 with Cache-Control, but no max-age, 14 with Cache-Control max-age too short (minimum 7 days), 0 with Cache-Control long enough, 14 complete.
A	Good: All checked attribute values are enclosed in quotation marks (" or ').
A	Good: Some img-elements have a valid alt-attribute.: 14 img-elements found, 3 img-elements with correct alt-attributes (defined, not an empty value).
	Wrong: img-elements without alt-attribute or empty alt-attribute found. The alt-attribute ("alternative") is required and should describe the img. So Screenreader and search engines are able to use these informations.: 11 img-elements without alt-attribute, 0 img-elements with empty alt-attribute found.
A	Good: Domainname is not on the "Specially Designated Nationals And Blocked Persons List" (SDN). That's an US-list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them. So if a domain name is on that list, it's impossible to create a Letsencrypt certificate with that domain name. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
