Column Layout Grid for Product Listing doesn't work with Firefox?

[CJPinder]

I have Nomo templates on templates and on modules
no error with that
in tempates/Nomo template/templates the only file on that folder is
tpl_modules_product_listing.php
and in modules/Nomo template the only file there, is product_listing.php

Very odd. You need to do some more digging around to see what the problem is because it sounds like your overrides for those files aren't working as they should.
