[SOLVED] different browsers show different colors

I have fixed my website

But this page shows the link above the title, top left, in grey in both Safari and Chrome, but in Firefox, it is the same color as the title:

http://oneworldnow.net/on-burchills-...r-her-benefit/


I put this code up:

body.page-id-2046 .p_title_class a:link, a:visited, a:active {
color: #666666;}


As you can see Firefox is the only browser that does not show the upper link as a lighter grey than the title of the article.

Why is this? How can it be fixed?

Thanks again!
