Script for opening website in default browser in fullscreen mode -

I would like to ask, if it is possible to make script for opening website in default browser in full screen mode. I have found some scripts but it was write for specific browser. So if I write it for chrome, and someone does not have this browser, script will not work. I tried something like this, but unfortunately it does not work. It opens the browser, but not in fullscreen mode.

 WScript.CreateObject("WScript.Shell").SendKeys("{F11}");
