Sign in to your SyncSellr account via the extension popup 2. Visit Facebook Marketplace or Gumtree and sign in normally 3. Click "Sync Cookies" in the extension popup 4. SyncSellr can now publish and manage listings on those marketplaces for you Key features: - One-click cookie sync for Facebook Marketplace and Gumtree - Automatic background re-sync every 4 hours - AES-256-GCM encrypted cookie storage - Only captures cookies from Facebook and Gumtree (no other sites) - No browsing history, page content, or passwords collected Requires a SyncSellr account at https://syncsellr.com
