So, I've been working on a sheet for a while now, and in Chrome it looks good, what with dif sections of the sheet being on dif tabs, but people who view the sheet through Firefox get bullet points instead of the 'tabs' look. Any one know why and/or how to fix this, I'm assuming it has to do with CSS as CSS tells it how to make those tab bits look, but it could, some how, also be the html (although I doubt that as it's a 'cosmetic' thing, everything functions properly still)
