ATF Cleaner issue

I have been following the read first instructions before I post any issue I may have with a virus.

I ran ATF Cleaner, and did the instructions for Firefox, about not deleting my passwords and such.

Now when I open firefox it has all changed into like a stoneage format. Some pages I cannot even navigate
or use. For instance my facebook page now look's like this.

Thanks in advance for this, I was hoping to see if I have a virus or something but have a few more steps in the sticky to complete first.
