Firebug can be used to troubleshoot styling issues in PHP websites by inspecting the HTML elements and their corresponding CSS styles. By using Firebug's CSS panel, developers can identify which styles are being applied to specific elements and make necessary adjustments to fix any styling issues. Additionally, Firebug allows developers to edit CSS styles in real-time, making it easier to test different styling solutions.
