If you’ve been using Firefox for a while, you may have noticed that some of your bookmarked sites have disappeared. This is because Firefox deletes bookmarks after a certain amount of time has passed. To keep your bookmarks around, you can use the following steps:

  1. Open Firefox and click on the three lines in the top left corner of the window. This will open a menu with several options.
  2. The first option is called “History.” Click on it to see how long ago each site was bookmarked. You can also click on “Delete” to remove them from your history.
  3. The second option is called “Bookmarks.” Click on it to see all of your bookmarked sites. You can also click on “Add” to add a new site to your bookmarks list.
