Embedded videos do not play since last Firefox verion for my Macbook

I recently upgraded to the latest version of Firefox on my Macbook Air running 10.14.6. When I try to play embedded videos, the video will freeze and there is a message saying that it is slowing down the page. I am in another country with a 50mbs connection and have to use a different browser to watch embedded videos. How can I return to the last version of FF which worked?
