Syncsellr Marketplace Coo

SyncSellr - Marketplace Cookie Sync enables furniture and vehicle resellers to manage listings across Facebook Marketplace and Gumtree from a single dashboard.

This extension syncs your marketplace session cookies with the SyncSellr web app (https://syncsellr.com), allowing the platform to publish and manage listings on your behalf. Instead of manually logging in to each marketplace, you sign in once in your browser and the extension securely captures and transmits those sessions.

How it works:
1. 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
