Hey there! To change the bookmarks menu to show the traditional list with folders, you can click on the three horizontal lines (the menu button) in the top-right corner of Firefox. Then, go to 'Bookmarks' and choose 'Show All Bookmarks.' This will open the Library window where you can see your bookmarks in the traditional list format with folders. Hope this helps you find your bookmarks easily again! Let me know if you need further assistance.
