YUI Connection Utility and Firebug
If you’re using the YUI Connection utility to upload files asynchronously, Firebug won’t show you the little "request being sent" message in the console. Since YUI is using an iframe to do the upload behind the scenes, Firebug won’t track it as a regular request.
If you want to make sure your request got through, add a console.log statement to the upload method in whatever object you’re using as the callback object for your connection. Otherwise, it looks like some kind of bug is preventing the request from being sent, when, in reality, it’s all working fine.
