how to fix it

Is YouTube not working? Have no fear, we’ll get you back to watching those cat videos soon enough. It’s possible that YouTube is down for everyone, but the problem is more likely on your end. Whether videos are endlessly buffering, the app isn’t loading, or something else entirely, our troubleshooting steps for Chrome, Android, and iOS should help you get YouTube working again.

Since yesterday, Youtube hasn't been working on Firefox. The page loads, but then the video itself just won't play. The black screen comes up and then a circle, saying it's loading but it just never does. I've tried: - Using Firefox in safemode, which caused YouTube to work again. I then re-entered the normal mode an disabled my only add-on (AdBlock Plus), but YouTube still didn't work. - Deleting my cache/history - Doing the windows+r thing, and deleting temporary files, which someone else on the website suggested - Refreshing Firefox None of these solutions have worked. On my 'plugins' section, Widevine something and OpenH264 something will be installed shortly, but I don't know if that'll change anything, and it's been saying that since yesterday.
