Can not open an embedded video on a website

I can not open an embedded video on a website that I use on a daily basis. It does open fine when I use Chrome.

Which site? sample link? @Me_Too

The site is a subscription service that I use.

Here is the link: https://www.simplertrading.com/chatroom-archive/options/09142021/

Is there a way to add an attachment or copy a screenshot?
