I'm a web developer and want to use Firefox, but am used to using Chrome for debugging. In Chrome debugging tool (hit F12 -> click 'sources' tab in top of the web dev window), you can clearly see the entire Javascript directory structure of the site you're visiting, and can collaps/expand directories nicely. How can I view the javacript directory structure in the Firefox debugging window? I can't do what I do without being able to easily navigate the filestructure of the website, but in the Firefox debugging window, all I can see is what appears to be javascript files in random order. Thanks! Josh
