Firefox v. 31.0 crashes when a user is logging in? (HFS 2.3b build 289)

[myrrdinstone]

Hi, I did an update to HFS 2.3b build 289 today in the morning. Then I used Mozilla Firefox v. 31.0 to visit my server and even I tried to logon Firefox has crashed. Is it an issue with the new version of HFS or is it an issue in Firefox?
BTW, I did a fallback to the previous version and it works again.

best regards
