Debugging Cognos Javascript

How do you usually debug your Cognos reports with embedded JavaScript? Mostly I develop in IE and then load whatever I'm working on up in Firefox and use the Firebug plugin to look for any errors. (mostly because Firefox 5 doesn't work for report studio (the menu buttons don't work?)). I think I'll put together a longer post on using firebug to debug Cognos issues, but does anyone use any other methods?

Oh, hey, there's my typo.
