CSS Browser Compatability Issue

[kman1985 0]

I have a header with a nav menu, a left sidebar float and a main-content float.. I just created a nav menu, it looks good in firefox but it chrome (and probabely others) the nav goes to the next line. The main content float drops under the left sidebar float, and the sidebar float looks indented.. On firebug In chrome I can decrease the padding of the nav menu and It'll fix it, but then in firefox it'll look off. I think it's a problem with widths and borders, idk. If someone could help me out that would be great.
