Click the Proxy Master icon in the toolbar → open Settings 2. In "General" tab, fill in IP, Port, Username, Password → click "Apply proxy" 3. The toolbar icon now shows "ON" — Chrome is using your proxy Import multiple proxies: 1. Go to "Proxy list" tab 2. Paste one proxy per line in "IP:Port:User:Pass" format 3. Choose type + optional group name → click "Add to list" 4. Click ✓ Check on any row to verify it works and see the ping Route only specific sites through proxy: 1. Go to "Website rules" tab 2. Add domains to the top box (whitelist) — only these will use the proxy 3. Or add to the bottom box (blacklist) — these will always bypass Sync setup to another Chrome profile: 1. On source profile: "Backup & Sync" → "Create sync code" → Copy 2. On target profile: "Backup & Sync" → "Enter sync code" → Paste → Import 3.
