Cleantube is a free Chrome add-on developed by sriram.vuppuluri. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. As the name suggests, Cleantube aims to enhance the YouTube viewing experience by providing a better CSS (Cascading Style Sheet) for the website.

When watching a video on YouTube, it can be frustrating to scroll through the suggestions shown beside the video, as it requires scrolling through the entire page. Cleantube addresses this issue by adding a custom CSS that allows users to view the video and the suggestions simultaneously.

With Cleantube installed, users no longer have to miss out on the content of the video while scrolling through the suggestions. This simple yet effective extension enhances the usability of YouTube, making it easier and more enjoyable to navigate through the platform.

Overall, Cleantube is a useful Chrome add-on for YouTube enthusiasts who want to optimize their viewing experience by ensuring they don't miss any part of the video while browsing through related suggestions.
