i do know that i have this (recursiv) call to the function again on success... but thats how it should work.
getScript seems to be just a kind of ajax call and, because of that, should be asyncronous. so in my understanding of this function there should not be this kind of behaviour - when you use other ajax calls the browser finishes loading althoug you do repeating ajax requests in your $(document).ready() function. another point is that i wrapped the getScript calls into $ (document).ready(), so the browser should have finished loading before starting the polling. but firefox even does not finish building the dom and so no use of firebug is possible.
