Is there a way to block a specific website using Firefox?

I know there has to be. Can anyone link me to where I'd need to go to do so, or give me a quick run-down?

I really need to block a website for my blood pressure. I'm seriously not kidding.

One guess as to the website. (Revealed in comments.)

They're all assholes. And the entire site is even more of a joke since they were brought out by Bravo. Like, for instance, one of the few forums I visit anymore is for the Real Housewives of Orange County/New York. Those shows are like the wet dream for what that site is SUPPOSED to be about. But, FOR NO REASON GIVEN, the RHONY board was closed, and the other one is always being shut down for weeks at a time. They don't say why, don't answer when people ask, and if they do say anything about the boards, it's to warn people for going off-topic, but really, that's not the issue for why it's closed and everyone knows it. It's because people snark about the women on the show and since it's Bravo related, they're quick with the fist. It's pathetic.

The site is nothing of what it claims to be. All of the mods there are so self-important and pompous. You're only better off for blocking it completely.
