Cursor has already rolled out support for Claude Sonnet 4.5. It is also now able to control your browser? What does that mean? Agent can now take screenshots, debug client issues, and improve your UI. For example, you can ask it to validate contact forms. How to enable it? Simply update to the latest version, and enable Cursor Browser.
