Why I cant Play YouTube Videos In Firefox?

Hello friends. This is my first post here. I am posting this for an issue with my Firefox browser. First and foremost, I’d like to state that I’m a business management student who spends the most of her time studying online. As a result, I’ll have to watch YouTube tutorials. For a couple of days, I am unable to watch YouTube videos on the Firefox browser. Because, after several attempts (the source is here), I am unable to open YouTube on Firefox. Guys, I don’t understand why this is happening and how to solve the issue. Can you provide any suggestions for this?

You’ll likely get a better solution from your operating system support channels.
