Method 1 (most likely issue) - Bookmarks toolbar is hidden: Right click on a blank spot near the top of your Firefox window and under '''Bookmarks Toolbar''' select '''Always show'''. Method 2 - You or Firefox accidentally moved the bookmarks somewhere else: 1. Go to the Bookmarks Manager in Firefox ('''Ctrl'''+'''Shift'''+'''O''' or ☰->'''Bookmarks'''->'''Manage Bookmarks'''). 2. Check all folders and subfolders under '''All Bookmarks''' to see if your bookmarks are there. 3. You can copy the bookmarks back to '''Bookmarks Toolbar'''. Method 3 - Check Mozilla Bookmarks backups (more complete search than Method 1): 1. Go to '''about:support''' in your address bar and search for "'''Profile Folder'''" and click the '''Open Folder''' button to the right. A folder should open up. 2. Go to the folder named "'''bookmarkbackups'''". There may be a ton of files inside, but don't panic. Select one that looks the most promising (large file, recent date). 3. Open it with a tool like https://www.jeffersonscher.com/ffu/bookbackreader.html. 4. If your bookmarks are not there, check another one of the files inside "'''bookmarkbackups'''".
