Hello CB,really hope you may be able to help me with this one. I have done plenty of testing and messing about with Firefox and still can't find a solution.
FYI I dont use YooTheme like a previous poster on the issue, and therefore don't have "WidgetKit".
I basically have 2 sites similar set-up. Both use CB Activity. When I paste in a YouTube Share Url using Firefox 47 as my browser -> one acts as expected and the other doesn't.
Notes: I have tried using F12 there are no JS errors shown, I have turned on Joomla error reporting and debug where to my knowledge nothing is flagged. I have tried switching templates to Beez3 and the result is the same. I have used a different laptop and same results.I have used Firefox in safe mode and same results. Both work as expected with Chrome.
The results of F12 -> NET -> Plugins is attached. The first one is the site where this works fine and the second it doesn't work. Doesn't work - meaning it pulls the info i.e. title of video, contols show including large play button, but shows black screen.
Extra notes: weirdest thing is the site where the video won't show HAS actually shown the video on occasion e.g. once today as first viewing after logging in. Reloaded page and it wouldn't work again. I have updated my firefox plugins e.g. flash player, firefox is most recent. I have tried an additional plugin where I can choose flash or html5 for viewing. I have also updated CB and all CB plugins and modules today on each site.
I suspect it has something to do with flashmediaelement.swf. I'm at a complete loss, do you have any suggestions?
Edit: the one that works has an SSL certificate - is this maybe the difference?
