Chrome Simulator is a Firefox browser extension designed to seamlessly mimic Google Chrome's user agent. This tool stands out in the crowded market of user agent spoofing extensions by allowing users to selectively disguise their browser identity on specific websites rather than universally. This targeted approach enhances compatibility and user experience while browsing.

One of the key features of Chrome Simulator is its automatic updates for the Chrome version it simulates, ensuring users are always using the most current user agent string. It achieves this by querying a simple API every 24 hours. Additionally, the extension simplifies the process by automatically detecting and configuring the appropriate operating system, while also populating extra JavaScript properties to pass common browser checks, such as navigator.vendor and the global chrome object.
