1. Disabling Video Annotation (clickable box)Annotation is a clickable box that overlays on top of YouTube videos. It aims to improve user engagement by displaying extra information or links related to the videos. It is useful for the video uploader, but can also be quite annoying for the users.
You can disable annotations to all YouTube videos via the YouTube settings. Click your profile picture then click the gear icon (YouTube Setting).
On the left sidebar, select Playback and uncheck the Annotations and Interactivity option. Easy as that.
2. Force Buffering Of The Entire Video
YouTube actually buffers only 30 seconds of the total video length when the video is paused. When your Internet connection isn’t quite fast enough to load the video this causes a lag. To avoid this, you can force YouTube to buffer the entire video before you can play it through,
SmartVideo for YouTube is a tool that can help with this and is available as a Firefox Add-on and Chrome Extension. After you’ve installed it and opened a YouTube video, you will see an additional option at the bottom of the video, click Global Preferences, and tick the box for Smart Buffer, as shown in the image below.
3. Disable Autoplay
YouTube will immediately start playing a video you’ve just opened which can sometimes be annoying. To disable autoplay video on YouTube, you can use the YouTube Control Center Add-on in Firefox or Stop Autoplay extension for Chrome.
Hope now you can enjoy the youtube videos at its best..
