Is www.mozilla.org safe?

No. MalwareAnalyzer scanned www.mozilla.org on 23 Jul 2026 and returned a suspicious verdict with a score of 20 out of 100, categorised as credential-harvest. Treat it as hostile until it is re-checked.

How was www.mozilla.org checked?

A static pass resolved DNS, captured TLS and headers and followed the redirect chain, and where the standard tier allows, a headless browser rendered the page and recorded every request. Egress is SSRF-locked. Signatures that matched only page text are weighted far below one that matched a served file, because a page documenting malware matches the same rules.
