All but one ? Rated 5 out of 5 stars

I know RightToClick as I know most of the author's add-ons for Firefox, and RightToClick is no exception to the quality of all.
But I have a problem with one site, this one site by the way is noted as extremely inadvisable by Siteadvisor, and this site is :
dailynews7.tv

Here nothing except disabling javascript prevents a pop-up page from blocking access to anything but itself : not even RightToClick handles it. The pop-up appears when you exit the site, asking you to confirm : unable to avoid it ... I've tried switching on ALL options of RightToClick, nothing does it!

Gets on my nerves. Not that I am fond of the site (I've discovered it today by accident), but I dislike stubbornness unless within humans :)
