Always document that thing that seems stupid at the time.
I had restarted my pc, went to the kitchen to make dinner and when I came back, I opened FF.
Well, my header wasn't appearing.
Then I logged in to MT, and it was all crazy mixed up colors and displayed wrong.
So off I went searching for the answer, when I had the answer all along.
I remembered that the same thing had happened to me back in March, so I used my sites search feature, and typed in Firefox.
There it was, clear the cache.
I cleared the cache, and voila all back to normal.
D'oh!
