Ready-to-paste prompt

Launch the browser with a custom User-Agent fingerprint by modifying the 'config.json' file: '{"userAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.3"}'

Heads up: Ensure you have the latest version of Node.js (14 or higher) and Chromium installed on your system, as the browser is built on top of these technologies
