When using Mozilla Firefox (16.0.2) I'm unable to click on the "unlock further protect options" when I want to move-protect a page. It only happens on the Dutch Wikipedia so far I think and I have no problems with IE. See for example here: https://nl.wikipedia.org/w/index.php?title=Hoofdpagina&action=unprotect.
