I am a web developer. On one of my sites there is a cascading drop menu to select State / City. This was working as of Firefox 3.6.13 and when I updated to FF4 it no longer works. It still works in Safari and IE. I do not even know where to start looking in the code for what may be affected. The way it is supposed to work on the page of the listed URL is you select a state from the first drop down, then the second drop down is populated with available cities for that state. Normally this takes about a second to display the list of cities, but now it sites on the "Loading cities" prompt and goes no further. Is this a bug in FF? I notice that FF4 is a little more "Chrome" like, so I checked it in Chrome to find that it does not work there either. If there was a way to attach the javascript code that creates the menu I would so that you could see what may be tripping it up. Let me know if you need additional information.
