FireFox scollbar ... always there?

Tired of seeing the site jump back and forth from "non-scrolling" pages to scrolling pages? Throw this in your CSS:

html {
overflow: -moz-scrollbars-vertical;
}

Now there is always a vertical scroll bar (even "grayed out") present and the site stays in position. No more kitters. No more wondering if the CSS code is correct or did something change...

Done!
