YouTube Customizer is a Firefox extension designed to improve video organization on your YouTube home feed. It allows users to customize the number of video thumbnails displayed per row, ranging from 1 to 12. This feature addresses a common issue where YouTube displays only a limited number of videos per row, often resulting in oversized thumbnails that can disrupt the viewing experience. The extension is particularly useful for users who prefer a more tailored interface while browsing YouTube.

In addition to modifying the layout of video thumbnails, YouTube Customizer offers an option to hide shorts from the feed, further refining the user's experience. With a subscription-based model, users can easily install the extension and adjust their settings to create a more enjoyable and personalized YouTube environment. This tool is ideal for those looking to enhance their social networking experience on the platform.
