Re-FreshView for YouTube is a Firefox add-on designed to improve your YouTube browsing experience by managing the visibility of videos you've already watched. This tool allows users to hide viewed videos, making it easier to discover new content without the clutter of previously watched entries. The add-on features a simple interface where you can control the visibility of videos using the Hide Videos checkbox and set a minimum watch threshold for what counts as 'viewed' through the View Threshold slider.

To utilize Re-FreshView, users must be logged into a YouTube account with watch history enabled. The add-on requires permissions to access browser tabs and modify displayed content on YouTube. This ensures that the tool can function effectively, helping users curate their viewing experience without any financial commitment, as there are no donation requests associated with it.
