 <p>this is a problem with the lastest versions of Firefox and not your code. I have half a dozen sites that are not properly rendering css in firefox at this time. they were all fine not more than a week ago and no change to the code or codebase was made. the styles still work in other browsers. </p> <p>Firefox is having issues on thier current release of the browser and I am sure they are all aware of it, but really, if it does not get fixed soon, they will loose even more market share. which would be a shame really.</p>
