Pop-Up Messed up in FF

I have a pop-up size named in IE and it works perfectly, but when i put it in Firefox, the size it messed up, here's my code:

window.open(linkhere,'name','width=500,height=400,location=no,menubar=no,resizable=no,status=no, scrollbars=no,toolbar=no');

thanks

Looks fine and works fine* for me in FF/Mac.
Can you post the surrounding script and an example of the markup/event where you trigger the function?

(* there should be no spaces within the window dfeatures string, but that may have been inserted by the forum post software. Either way, the spaces don't actually stop the method from working in FF/Mac, though they should certainly be avoided.)
