CSS - List style problem with Firefox

[marra]

All my lists are styled with list-style-type:disc; and the bullets are showing up in Internet Explorer but not Firefox. I'm getting quite frustrated trying to get it to work. Can anyone think of a reason why it might be doing this without me having to post all my code?

They're not showing up at all. I have them set not to show up in my menu class but this shouldn't affect them in my content should it? I'm completely stumped.
