Cannot play flash video Care2 ecards?

[phd21mint]

Hello Slimjet,

First, Merry Christmas and Happy Holidays to everyone at Slimjet !!!

I love this browser! I am using Linux Mint KDE 18.2 based on Ubuntu 16.04 and Linux Mint KDE 17.3 based on Ubuntu 14.04. But today in my Linux Mint 18.2 system, I went to send ecards from Care2 and got this message below? I have adobe flash installed and pepperflash, etc...
https://www.care2.com/send/card/5671

"You do not have
Adobe Flash v.9
or above installed.
Without it, you will not be
able to view your eCard.

I went into the "i" section to the left of URL and told it to allow flash for this website, and now I can see the image of the video, but it will not play? Firefox 57 works with this website?

Best regards,

Phil
