Site design seems to be undergoing some changes. That made a mess of FireFox presentations for me. Like you say, clearing the cookies and returning made all better. Now to get used to the new design...
Yep, quick refresh will fix it. If you look carefully, you'll notice we made some subtle changes to the header. We got rid of the Weekly Contests countdown clock, moved the search to the bottom row of links and gave it a bigger field, and made the latest os and device superpages links more prominent.
couple little glitches we're fixing at the moment, but a quick refresh should fix any temporary load glitches

The back button is working for me.
I had to clear my cache and cookies also. I could not read anything in Firefox either, but after clearing cache/cookies, the page renders properly in Firefox.
