Youtube Video Issue

more options

I have a Mac running High Sierra. I have FF 72.0. Usually, I use Private browsing to delete my stuff.

1. I can't watch any Youtube videos. It comes up with a black screen and nothing else. How do I fix it? 2. If I roll back to 65 then Youtube videos work and no issues. How do I disable FF from auto updating?

Again, if I stay on 72 then I can't watch videos unless there is a fix. If I go back to 65 then it works.

I also have 2 questions.

First, I don't know where to start a new topic. It is only showing the option to reply. So, I will reply here. I want to post about a message I am getting from Firefox. Can someone tell me how to start a new thread?

I would like to, but I don't see a way to post a new thread. Can you tell me how to do this? It is only giving me options to reply to existing posts.
