GWT SuperDev - Can't find GWT Modules

You need to click the bookmarklet when viewing your compiled web app.

The last steps should therefore be:

• Dragged Dev Mode On to firefox's bookmark.
• Switched back to my application at http://localhost:8888/SuperDev.html and clicked the bookmark

Once you have the bookmarklets, you actually don't really need to open http://localhost:9876 anymore (you'll find compile logs there, and can browser your code, including the code generated by GWT generators; so it can still be useful).
