This Firefox extension helps keep your bookmarks up-to-date by automatically detecting and updating URLs that have been redirected. When a bookmarked URL is redirected to a new destination, the addon replaces the old link with the updated one. It also removes the outdated URL from your bookmarks to ensure that you always have quick access to the most current web page. This tool is particularly useful for users who manage large collections of bookmarks and want to avoid broken links or outdated entries. With this addon, your bookmarks stay organized and relevant without any manual effort.

This extension is also available for Edge Browser
