Is floccus safe?

Clean risk

Syncs bookmarks across browsers and devices using a storage backend you choose.

This extension synchronizes bookmarks between supported browsers and devices, including Chrome, Firefox, and Edge. It lets you configure a backend such as Nextcloud, Linkwarden, KaraKeep, WebDAV, Google Drive, or Git, with optional end-to-end encryption for WebDAV and Google Drive. Its permissions allow access to bookmarks, tabs, tab groups, browser storage, identity, alarms, and websites for sync-related operation.

Shared hosts - 23 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
