I actually have this same problem. Some of my videos don’t display when I use firefox on my laptop, but display fine when I use firefox on my PC even though they are the same version of FF. If I use IE or Chrome on my laptop the videos are there. Also using version 2.7.1
This is a good example –> https://www.shazbot.com.au/?cat=27
The top video shows, but the 2nd and 3rd don’t.
If you have found an answer since your last post? please reply and let me know.
