Editors' Note: The Download Now link will prompt a local download of the Firefox extension. To install the extension directly, open the file using your Firefox browser.
You can use the JSView extension to solve the problem. You can access JSView from the context menu, from the toolbar, from the view menu, or from the status bar. With JSView you can now view the embedded css and js as well. There will be 3 new tabs in that window. One for scripts, one for stylesheets, and one for frames. You can open them by double clicking or by using the context menu.
