DF Tube is a Chrome add-on developed by calkuta. It is a free tool that aims to help users focus while using YouTube™ for work, recreation, or education.

The add-on allows users to remove distracting elements from YouTube™, such as advertisements, video recommendations, and comments. By default, DF Tube disables autoplay, hides the video recommendations sidebar, related videos at the end of videos, and the grid of recommended videos on the homepage. These settings are configurable, giving users the flexibility to customize their YouTube™ experience.

DF Tube is designed to break the cycle of mindlessly clicking, watching, and scanning for new videos. It provides a clean and distraction-free environment for users to focus on the content they want to engage with.

Regarding privacy, the developer emphasizes that they do not read, examine, or track users' browser history or any other personal information. The only permissions required are "tabs" to insert functionality and "storage" to store user settings. The developer is committed to privacy and assures users that the extension is solely a tool to remove distracting elements from YouTube™.

Overall, DF Tube offers a simple and effective solution for those who want to eliminate distractions while using YouTube™. Give it a try and provide feedback to help improve the add-on.
