That's the result I'm getting. Can you reproduce the problem in a brand new profile with the latest Nightly?

Hello Mark, thanks for filing a bug.

I think you are bitten by Bug 1371936, which is fixed in Nightly (and in Beta/DevEdition next week I think). Hence, I am going to close this bug as a duplicate, but feel free to reopen it if you think there is an other issue.
