I actually don't think that this is trivial.

I think Gleb's suggestion setting window.location is the right approach.
It might be an idea to consider a hidden iframe for this, but you have to
also take care of error handling and issues with mime types (e.g. when the
browser wants to render the download).

In general, you shouldn't do this. Use asynchronous requests.

This will not help you, I guess, as remote requests deliver data to your
script, and do not trigger the browser to render them or open a Save As
dialog. In your script, you have e.g. no way of saving the data to disk.

Did you really check the Net tab of Firebug? Even then, depending on your
Firefox/Firebug version, you might not see all the requests going out. A
better check for that are local web proxies, like Fiddler on Windows or
similar.
