Auto-Quit from Browser Window

Is there a way to auto-quit after a movie is done playing in the browser window? We have a "Quit Button" which you can click on and then that pulls up another movie clip which displays a disclaimer for 5 seconds, then turns off. When the disclaimer is done being shown, I want it to completely exit out of the browser window, like it does in the player.

I don't have anything to show you because this is for the company I work for and obviously can't upload it.

So to break it down:

1 - Click on quit button

2 - Disclaimer Movie clip plays for 5 seconds

3 - Currently loops again (but what I want is for it to close out the window it is currently in).

Thanks in advance.
