CurbPage

CurbPage consolidates web navigation into one privacy-focused extension. It manages bookmark profiles with tags, provides a full TOTP/HOTP authenticator, stores encrypted passwords, offers relative-link shortcuts, and showcases CurbApps browser themes. Everything is stored locally in SQLite. OTP secrets and vault credentials are encrypted under your account key, while synced product data is end-to-end encrypted before it leaves the device.

Nothing leaves your device unless you choose to sync. The one exception is Premium bookmark classification, which sends only a title and URL, never page content, and encrypts the result before it syncs.

Core features

• Bookmark profiles: keep separate sets of bookmarks for work, research and personal use, and switch between them instantly.
• OTP authenticator: TOTP and HOTP codes, added by QR scan or manual entry, encrypted at rest.
• Password vault: save, generate, search, reveal, and copy credentials encrypted under your account key.
• Relative links: save reusable path patterns that resolve against whatever site you are on.
• Theme gallery: browse CurbApps browser theme palettes.

Free vs Premium

The free tier covers three profiles and every core feature. Premium unlocks unlimited profiles, per-profile passwords, encrypted export, cloud classification and opt-in sync.

Importing a YouTubeExt bookmark profile

YouTubeExt bookmark files use the same plain and password-encrypted JSON formats accepted by CurbPage. If you already have a file, open the CurbPage popup and use Import profile. Keep the original export password because CurbApps cannot recover it. The archived YouTubeExt popup has no export control, so there is no normal UI migration. The retirement handoff explains the limited recovery path for an installed development copy.
