Features & Capabilities

Nextcloud Bookmark Sync is a privacy-first extension that allows you to sync your bookmarks using your own Nextcloud server via WebDAV.

Say goodbye to Big Tech's cloud services. Keep your bookmarks perfectly synced across Firefox, Brave, Chrome, and Edge without your data ever leaving your control. The extension creates a dedicated "🔄 Bookmark Sync" folder right in your Bookmarks Bar for easy, isolated management.

✨ Main Features:

🔒 100% Sovereign & Private: No third-party servers, no analytics, no tracking.


🤖 Automated Background Sync: Detects local bookmark changes and automatically pushes them to your server. Pulls updates in the background based on your preferred frequency.
🗑️ Smart Archive System: Deleted bookmarks are never truly lost. They are safely moved to a "🗑️ Bookmark Archives" folder that intelligently positions itself right next to your sync folder.
♻️ Auto-Cleanup Retention: Archives are neatly organized by date. A daily background task automatically cleans up archives older than your custom retention limit (adjustable from 1 to 30 days).
🎯 Exact Ordering: The precise visual layout of your bookmarks and folders is perfectly replicated across all your devices.

🛡️ Smart Collision Protection: Uses a custom Mutex lock mechanism (.lock files) via WebDAV to ensure your data is never corrupted, even if two browsers try to sync at the exact same millisecond.

⚙️ Prerequisites: You must have a running Nextcloud instance and generate an "App Password" in your Nextcloud security settings to use with this extension (Do not use your main Nextcloud password!).

Is Nextcloud Bookmark Sync Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Nextcloud Bookmark Sync requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Nextcloud Bookmark Sync is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
