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: http://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode 2) try this with a clean profile: http://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
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.
