Profiler requires a debug build, not an release build. Are you sure the app is a debug build?
Usually, you point at an html or swf file and not an mxml file

Thanks for quick reply.
Actually this was my typo, i am pointing to swf file.
I have enabled the debugging option by setting the <verbose-stacktraces> to true in flex-config.xml, but when i run the swf on Mozilla Firefox the debugging option is disabled, so it seems the swf is not built with debug on. Is there any other way to enable the debugging option?
It is a silly question but do you have the Firefox debug flash player version installed?
My problem is solved, now i am able to start my application in debug mode.
Thanks again for your help.
