Hi,
Hope everything is going well.
Increasing the buffer size in your browser for video playback can help improve streaming quality on various websites. While there isn't a direct setting in most browsers to adjust buffer size, to improve video buffering, you can clear browser cache and cookies, ensure a stable internet connection, close background applications, and consider upgrading your router or internet plan.
