Question

I’m simply opening a popup from JavaScript with the settings you can see in the code. Works fine in Firefox. In Opera it’s opening it in a new tab instead. Why?

Here’s a JSFiddle:

The number of parameters doesn’t seem to make a difference. Either work in Firefox and IE8. (Don’t have IE9 or Chrome to test right now.)

I tried googling… can’t find anything. I don’t even see anything here that mentions it, yet it’s clearly working in their examples: http://www.quirksmode.org/js/popup.html

Thank you for any help.

There is problem with spaces in options param:

window.showPopup = function(){
    window.open(
        'http://placekitten.com/600/500',
        'thePopup',
        'width=600,height=500' /* <------- Look, no spaces and works */
    );
}

It is still a tab, but with different dimensions. So, it looks kinda as popup.
