Hello, Firefox automatically creates backups of your bookmarks, which can be helpful if your bookmarks are lost or missing. To recover them, follow the instructions below. #Use <u>one</u> of these methods to open the Bookmarks Library window: #* '''Firefox 29 and above:''' Click the Bookmarks button [[Image:Bookmarks-29]] and select ''Show All Bookmarks''. #* '''Previous Firefox versions:''' Click the [[Display the Firefox button menu instead of the menu toolbar|Firefox button]] and click on ''Bookmarks''. (If you don't have a Firefox button, click the Bookmarks button [[Image:Bookmarks button win 2]] or ''Bookmarks'' menu item and select ''Show All Bookmarks''.) # At the top of the Library window, click on ''Import and Backup'' and select ''Restore''. # Click the date of the bookmark backup you want to recover. # In the new window that appears, click OK. # Your bookmarks from the selected date should now be restored. For more information, see the [[Restore bookmarks from backup or move them to another computer]] article. For other solutions, see the [[Recover lost or missing Bookmarks]] article.
