The default styles are overridden via custom style sheets. Under Firefox 2, IE 6&7, these overrides behaved consistently and as expected, the custom stylesheets were always given precedence. However, on Firefox 3 the stylesheet ordering appears to be inconsistent. Upon loading a page, the override classes will be loaded before the defaults and the page will look incorrect. Then on refresh the override classes will be loaded after the defaults and the page looks correct. Subsequent refreshes will be inconsistent. Unfortunately the site in question cannot be provided for testing but please let us know how we can be of assistance in any way. Reproducible: Always
This can only be tested if you attach a testcase (with the Add an attachment link).
Reopen if you're able to provide a simple testcase that demonstrates the bug. Otherwise, you can hope that (1) it's a bug in Firefox rather than a bug in your site and (2) someone else also hits it and reports a bug :)
