Question 1

Is mozilla.org secure?

Accepted Answer

Website Auditor grades mozilla.org based on HTTPS, TLS, HTTP security headers, cookies, DNS, email authentication, reputation feeds and information disclosure. Check the score above for a quick verdict and the module list for specifics.

Question 2

How is the Security Score for mozilla.org calculated?

Accepted Answer

The score is a weighted composite across six categories: Security (headers, TLS, cookies), Infrastructure (DNS, DNSSEC, redirects), SEO (indexing, canonicals, structured data), Email (SPF, DKIM, DMARC, MTA-STS), Performance (Core Web Vitals via PageSpeed) and Trust (reputation, blocklists, phishing feeds).

Question 3

How often should I re-scan mozilla.org?

Accepted Answer

After every deploy that touches infrastructure, DNS or headers, and at least monthly. Use the Rescan button above to run a fresh audit — results are re-fetched live, not cached.

Question 4

Does Website Auditor store scan results for mozilla.org?

Accepted Answer

We keep a lightweight scan history (score, grade, timestamp) so you can see trends and share a public report URL. Raw response bodies, headers and cookies are not persisted or sold.

Question 5

What does a failing check on mozilla.org actually mean?

Accepted Answer

A fail means the check falls short of a current best-practice baseline (for example, a missing Content-Security-Policy or an expired TLS certificate). Each failing item includes the current value, the expected value, and a concrete recommended fix.

Question 6

How do I fix the issues found on mozilla.org?

Accepted Answer

Scroll to the "Fix mozilla.org with AI" card at the bottom of this report. It generates a copy-ready prompt with every failing and warning check, grouped by category, that you can paste into ChatGPT, Claude, Gemini, Lovable or Cursor to get exact code and configuration changes.

Question 7

Is this audit safe to run on mozilla.org?

Accepted Answer

Yes. The scan only issues a small number of standard, unauthenticated HTTP(S) and DNS lookups against mozilla.org — the same requests any browser or search-engine crawler would make. It does not attempt exploits, brute force, or write operations.

Question 8

Can I embed the mozilla.org security grade on my own site?

Accepted Answer

Yes. Use the "Embed your grade" card above to copy an HTML or Markdown badge snippet. The badge auto-updates whenever mozilla.org is re-scanned.
