On entering the site - http://smouch.net/lol  Firefox moves round the screen due to an active JavaScript exploit.A flash video begins to play and if I click on the close tab button a Message box driven by JavaScript begins to Pop-Up.The box has only two options i,e, OK and Close.On whatever I click, it reappears with a different message.Same thing happens if I want to close Firefox by clicking Close (Window) button.Thus, to close the site, I have to click on the Message Box about 25 to 35 times and then it finally closes. This also happens in Internet Explorer 7. But Opera 9.5 remains unaffected with this problem.Please fix this problem.It is certainly a Browser Exploit.

It should have closed the Broser Window or Tab as usual.
