Please refrain from opening the popup unless the user really wants it, otherwise they will curse you and blacklist your site. 😉
edit: Oops, as Joren Van Severen points out in a comment, this may not take into account taskbars and window decorations (in a possibly browser-dependent way). Be aware. It seems that ignoring height and width (only param is fullscreen=yes
) seems to work on Chrome and perhaps Firefox too; the original ‘fullscreen’ functionality has been disabled in Firefox for being obnoxious, but has been replaced with maximization. This directly contradicts information on the same page of https://developer.mozilla.org/en/DOM/window.open which says that window-maximizing is impossible. This ‘feature’ may or may not be supported depending on the browser.
