Smart bookmarks folders are saved searches of your bookmarks and history that appear as folders in your bookmarks. For instance, you can create a folder that lists all bookmarks you visited the day before; and it is updated automatically.

• To make a regular bookmark folder, see Use bookmark folders to organize your bookmarks.

Pre-installed smart folders

Firefox comes with some smart folders available:

• Most Visited: Available from the Bookmarks toolbar, this folder lists pages you have visited the most number of times.
• Recently Bookmarked: Available from the Bookmarks menu, this folder contains a list of the last several bookmarks you've added. Expand the Recently Bookmarked folder to see a list of sites.
• Recent tags: Available from the Bookmarks menu, this folder keeps track of the bookmark "tags" you've used most recently. Expand the Recent Tags folder to see a list of tags, then expand each tag to show pages you've recently bookmarked using that tag. For more information on tags, see Bookmark Tags - Categorize bookmarks to make them easy to find.
  
  

If you accidentally delete one of these Smart folders, see Restore the default Smart Bookmarks Folders.
