This is a brilliant script. Not only it keeps the header fixed, but also provides a great 'top link' feature.
A little bug: The 'Find Friends' link isn't hidden in Chrome when the option is selected.
Thanks for the updates as well!
Thank you for writing this one. I've always hated how Facebook does not have a static header. I just installed it and love it.
This was the format that Facebook had late August, 2011:
This script fixed it and improved other features. However, when I first tried it, I couldn't DL it to Firefox 3.6.21. I upgraded to FF 6.01, did the DL and now the script works in FF 3.6.21 also!
Great work, thank you.
