Install Flash Player without administrative permission

Let’s assume you’re at work or at school and you’re on the computer. There’s an enormous chance that you have no administrative priviliges and there’s apsolutely nothing you can install onto the computer. Let us also assume that you want to use Mozilla Firefox instead of IE. That’s an easy one, ’cause we’ve all heard of Firefox Portable. Finally you download Firefox and you’re happy how you fooled Windows. So you’re browsing and you go to youtube. And what happens? You need to install the Flash Player. Damn… What now…
1. Copy this link (http://fpdownload.macromedia.com/get/flashplayer/xpi/current/flashplayer-win.xpi) into Internet Explorer and save the file. *why to IE?.. because if you just try to download it with Firefox, everytime you try it, the automatic addon-installer will appear and that is not what we need)
