On a proof I’m mocking up, there is a random space forcing a horizontal scrollbar that I cannot find the cause of. Oddly enough, this is only happening in Firefox (16 – Mac + PC). If you load up that page, you’ll see a black line on the right of the page (in the “header” area). Firebug isn’t helping much here and only seems to go away when I clear the contents of the main .container. I’m honestly a bit lost here as I’ve never seen Firefox of all things give me trouble. Any help would be greatly appreciated. Thanks!

styles.css (line 764) — remove
right: -25px;and it goes away… Hope it helps!Looks like it doesn’t affect anything visibly either.
