What our analysis found

Markdown Preview Plus, used by 90,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites. It comes from a trusted publisher and was last updated in June 2026.

Analyst notes

The extension's code matches its stated purpose: converting and rendering markdown files with live reload, themes, and diagram support. All network requests (autoreload fetches from the page's own URL, PlantUML rendering, optional user-configured external CSS) serve legitimate features. Content is sanitized with DOMPurify before insertion. The clipboardWrite permission is used only for explicit user-initiated copy. No unauthorized data collection, obfuscation, or remote code loading was found. The third-party 'malware fingerprint match' is likely due to common open-source libraries (marked, purify, etc.) also present in other extensions. Publisher is Google-trusted with a valid privacy policy.
