I have a select box that calls window.open(url) when an item is selected. Firefox will open the page in a new tab by default. However, I would like the page t
window.open(url)
You don't need to use height, just make sure you use _blank, Without it, it opens in a new tab.
_blank
For a empty window:
window.open('', '_blank', 'toolbar=0,location=0,menubar=0');
For a specific URL:
window.open('http://www.google.com', '_blank', 'toolbar=0,location=0,menubar=0');
