Problem with bullets

Have a look for a second definition in your style-sheets, perhaps something like a background/img definition for li?

The problem is with Internet Explorer, which isn’t doing what your stylesheet is telling it to do. Firefox is correctly interpreting your stylesheet.

If you look for something like li:before {
content: "0BB 020"; on your stylesheet, that’s what’s calling the quotes. IE’s just too dumb to be able to handle that, and so defaults to a disc. But you’ve set the list style to “none”, and so you’ve told IE not to display any default style if it can’t handle what’s specified in the css.

Anyway, that’s the bit you need to change or delete.
