It does not work

(Revert Site) still works.

Excellent!

Switch back to the old one!

Sadly it's main function which was giving us the old Facebook layout back no longer works, due to Facebook blocking that from happening via a code change. But it is still a recommended add-on that's worth using, as this at least makes the horrid, new Facebook design a bit better on the eyes by bearing a resemblance to the way it was before. That despite even if it's now down to just strictly a cosmetic thing which merely puts lipstick on an ugly pig, and nothing more. It'll sort of help you get used to the new layout a bit better, and easier, as difficult as that'll be to do for at least a long while. That being the case with the site now becoming barely functional after this no good, unneeded drastic change it made now.
