Screen freezing completely when watching YouTube videos

When I was watching a YouTube video on Zorin OS 16.1 Core, the system suddenly completely froze. The audio looped the last few seconds before the freeze. This has happened multiple times in a day and I had to force my computer to shut down. Please help. Thanks.

Oof... ultra widescreen.

Are you using any YouTube enhancement add ons?
Do you have "Hardware Acceleration" is enabled in your browser? If so, try testing with it disabled.
Is it 16 gigs RAM?

I don't have any YouTube enhancement add ons
Yes it is 16 gigs of RAM
I have disabled hardware acceleration in Firefox and now I shall watch some more YouTube videos.

With hardware acceleration turned off, I made it through 30 minutes of YouTube videos with no freezing, and with hardware acceleration turned back on, I also made it through 30 minutes of YouTube videos with no freezing.

I think I will keep hardware acceleration off for now.
