audio and video out of sync on all youtube videos

On every youtube video I watch, the audio and video go out of sync after about a minute. It has been happening for weeks now. I can make it go back in sync by pausing the video and playing it again, but it's annoying to have to do that every minute, especially for long videos. I tried turning off the html5 player in firefox, but it didn't work. I tried the flash player plugin for firefox, but the video was really choppy. I can't find any other fixes that apply to this problem.

I'm using firefox 50.0.1 and windows 10 (64 bit) version 1607. (I tried installing the updates suggested in the audio and video problems page on mozilla support for version 1607 64 bit, but when I tried to install them, they said they weren't applicable to my computer).

Youtube currently uses the HTML5 player.

The only thing I could do on that list is clear the cache. My drivers are up to date, and I tried to check my plugins, but the page sat there for about 5 minutes with the circle going around and around, and didn't load anything. The first video I watched after I cleared the cache (which was only 5 mb) and restarted firefox seemed to work, but then the on the next video, the sound went out of sync again.
