Thanks for those updates! Whats happening with Firefox here ?! The good thing here is that you have two backup options (IE and Chrome) for you to continue your work, but its good these cases are getting raised....
I have personally not come across this, but what I'd try before digging down further would be to remove and add the field in the account form (do this exercise in Firefox) and republish.
Is the status field a global option set or you have customized it only for the account form ?
