To debug a pop-up browser, first inspect the pop-up using your browser's Developer Tools (usually accessible with F12 or right-click > Inspect). Next, go to the Console tab to view any JavaScript errors. Use the Network tab to track requests that the pop-up makes. If the issue lies in custom code, set breakpoints in the JavaScript or HTML code within the Sources tab to pause execution and step through the code. Remember to clear cache and cookies to ensure you're not dealing with stale data. These steps will help identify and solve most pop-up related issues effectively.
