Scores Not Submitting Mochi & Firefox


I'll be honest, I've not really been paying much attention to websites, forums, arcades etc...I've moved on but every now and again I go back to my test site and mess things up a little. Maybe I have missed something or maybe I've missed a lot but I cannot seem to get Mochi games scores to submit using Firefox (21.0 or 22 beta 6). Occasionally the first score will submit but no other scores seem to submit, however, the same games score fine using IE10 or Chrome.

Is it just me or has anyone else had problems?
Hhhmmmm..... I don't recall a browser specific issue with Mochi. Are you running AdBlock+ or anything like that in FF?
