I just picked up a client with an existing site, and there is a an odd problem with Firefox...

The site uses the 960 grid system, but certain grid are not visible when loaded in firefox

The user has to refresh the page to see this. I may need to dismantle this, but I would rather not have to.

The issue is only in Firefox on OS X and Windows 7. I tested in Firefox 10.0.2

Hello,

It is not the grid itslef. It is your CSS.
Your color property is the same as the background color..

body, td, th {
    color: #EDE8EC;
}

Please change this to some other color or add a color here:

p {
}

as now it is empty.

Thanks, I appreciate you finding this. I just inherited the site... and found it odd that it manifested itself ONLY in Firefox.
