Youtube lagging every few seconds

The audio continues to play but the video stops. I've tried everything from Malwarebytes, disabling hardware acceleration and using the about:config.

Please also note that html5 may need to be enabled to view some videos on youtube https://www.youtube.com/html5

Please tell us if this helped!

Still lags on Youtube!

Please check the speed of your service provider, it might be easy to tell if you lower the quality of the video in youtube first.

download speed is 22.3 Mbps and upload is9.36Mps

Could you check whether you are using the built-in "HTML5" video player or Flash? Generally speaking, you can distinguish them by right-clicking the player.

There is an add-on which allows you to force one player or the other on YouTube and it might be worth experimenting to see which one works better/worse:
