Scripts are not allowed to close a window that a user opened. This is considered a security risk. Though it isn't in any standard, all browser vendors follow this (Mozilla docs). If this happens in some browsers, it's a security bug that (ideally) gets patched very quickly.
None of the hacks in the answers on this question work any longer, and if someone would come up with another dirty hack, eventually it will stop working as well.
I suggest you don't waste energy fighting this and embrace the method that the browser so helpfully gives you — ask the user before you seemingly crash their page.
