I was not been able to reproduce the issue. Could you please try the following, to see if you still reproduce the issue:

1) running in Safe mode:

2) try this with a clean profile:

I'm still able to reproduce the bug in safe mode with a clean profile.

Also reproducible in nightly builds ("Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:29.0) Gecko/20100101 Firefox/29.0").

It only happens on OS X, it seems.
