DFTube is a browser extension that lets you control what you see on YouTube. It can remove recommended videos, prevent videos from automatically playing, disable your homepage suggestions. I have noticed that it doesn’t always work, but generally it does a good job of hiding the feed and suggested videos.
This allows me to be less distracted by YouTube’s suggestions and focus on watching only things I search for. YouTube’s suggestions are very relevant and do a good job of getting me into a loop of watching video after video. This extension has saved me a ton of time by reducing the chance I watch a video I don’t really need to watch just because it’s recommended to me.
