In code review (v5.9.1)

Our reviewer read version 5.9.1 — the most recent version we have reviewed — and found no malicious behaviour. The version shown here has not been individually reviewed yet.

What our analysis found

floccus bookmarks sync, used by 100,000 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 September 2026.

Analyst notes

The extension’s permissions (broad host access, identity, bookmarks, tabs, etc.) align with its stated function of syncing bookmarks across user‑configured servers. All network communication is to endpoints chosen by the user (WebDAV, Nextcloud, Google Drive, etc.) or to Sentry for optional, privacy‑policy‑disclosed crash reporting. No evidence of unauthorized data exfiltration, code injection, or obfuscation beyond standard bundling was found. The ML model’s risk score is low (0.00), and third‑party risk indicators (featured, good rating, old extension, trusted publisher) corroborate a false positive.
