Safari and Firefox rendering differences- what to do?

I can’t see the difference between the two images. If your code validates and you are using current versions of the two browsers, the difference between them should be barely perceptible. A link to your site would be helpful.

I appreciate the reply Chris. The difference is in the nav bar top right.

Valid apart from 2 parse errors and a ‘property-moz-opacity doesn’t exist’. (Goes without saying I have no idea what this means.)

Other than color differences, I don’t see any problems in Safari or Firefox. You’re never going to get one browser to render a site exactly like another, and this is probably as close as you can expect it to be. It even looks OK in IE7. Nice looking site BTW.
