This approach may not work as it depends on how and when the browser performs its security checks. If I were to hazard a guess I would think that this approach would not work as it could be a security hole. As long as you can determine the method used to close the window you can manipulate the DOM to prevent it. I.e., at some point a script is deriving the window object. Figure out how and you can prevent it. But also keep in mind my previous caveat--doing so could cause the site to not function properly.

Oh the reason I want this functionality is that I have multiple accounts for dealing shares, every day I have to set up 3 different browsers and 10 or so different pages and it takes 10 minutes of my life every day. So I'm trying to find a way to do everything I need, open every page and account in 1 click.
