How can I set the window size using Javascript / jQuery?

Question

I'm trying to set the dimensions of the window to 500 x 500, but it's not working. What am I doing wrong?

$(document).ready(function() {
    window.resizeTo(500, 500)
})

Answer 1

You can resize only your own popup windows, not the main window:

Can't resize a window/tab that hasn't been created by window.open.

Can't resize a tab if the tab is in a window with more than one tab.
