Smart Folio от stainscode

Smart Folio replaces the default new tab with a private bookmark dashboard for Firefox.

Organize bookmarks into folders, search quickly, import your Firefox bookmarks on demand, detect duplicates, switch between light and dark themes, and export or restore your data with local JSON backups.

Smart Folio is designed privacy-first: your bookmark data is stored locally in your browser storage. The extension does not require an account and does not transmit your data to a remote server.
