Why is YouTube video lagging on Firefox? If you're facing YouTube lagging issues, then it's probably because of the extensions on your browser. Extensions are available to enhance your browser's functionality. However, sometimes, it causes more issues for you.

How do I speed up YouTube on Firefox? Control speed of the youtube playback using the keyboard. Press '+' to increase and '-' to decrease the playback speed. Or Shift + mouse wheel
