Storyline published content not loading in Firefox, all of a sudden

Thanks Jürgen,

This was my fear. This bug is affecting hundreds of storylines that have been published over the years in our curriculum.  Steven, yes both firefox and Storyline are up to date but because this issue affects previously published files, sharing any .story file to troubleshoot is not really relevant. Users are reporting this issue en masse today for the first time, so I was wondering if it is something new others are experiencing this week. I wasn't sure it could be related to the audio on the first slide issue that has occurred in the past. I have to do more checking, but I am wondering if there are other solutions besides republishing out there?
