The following javascript opens a pop-up in Firefox, Safari, IE, and Google Chrome:
window.open(\"http://google.com\", \"foo\", \"toolbar=yes,location=yes,men
The only option for Chrome is to not specify a third argument. Chrome ignores the third argument as they are rightly allowed to do according to the HTML 5 specification, but if present the window appears to always open in a floating widow without controls.
If you do not specify a third argument the window that opens will be a new tab and will have all of the features the user needs.
If you do specify a third argument you will get a new floating window with no controls other than the URL display.
