About this extension
Bookmark Sync merges the bookmarks of Chrome, Edge, and Firefox into one tree. Install the extension, sign in with the same account, and any changes you make on one device sync automatically to your other browsers—no manual import/export, no self-hosted server required.
【Key Features】
· Cross-browser sync: Two-way bookmark and folder sync between Chrome / Edge / Firefox. Organize on one device, and your other browsers update automatically.
· True tree-structure sync: Syncs the real bookmark tree instead of flattened path strings. Renaming folders, moving, and reordering keeps every child item and level intact, with consistent ordering across all devices.
· End-to-end encryption by default: Every bookmark operation is encrypted on your device before upload (AES-256-GCM). The server only stores ciphertext, so no third party—including the service provider—can read your bookmarks. Set one sync passphrase and enter it on a new device to decrypt and sync.
· Conflict-free merging: Concurrent add/edit/delete from two devices merge automatically; both sides' additions are kept, and offline changes merge once back online.
· Deletions never resurrect: Deletions propagate across devices as tombstones, so bookmarks removed on one device never reappear from stale data elsewhere.
· Multiple spaces: Create separate spaces to keep work and personal bookmarks apart, each synced independently.
· Device management: Registered browsers are listed for review; rename or unbind any device at any time.
· Free to start, no credit card: The free plan syncs up to 500 bookmarks with full functionality; upgrade whenever you need more capacity.
【Privacy & Security】
· End-to-end encryption enabled by default; the server cannot read your bookmark content
· Collects only your login email and the minimum data needed for sync
· Privacy policy: https://www.bookmark-sync.top/privacy
