To find if your bookmarks are in another location: 1. Go to '''☰'''->'''Bookmarks'''->'''Manage Bookmarks'''. Or use hotkey '''Ctrl'''+'''Shift'''+'''O'''. 2. Check under '''Bookmarks Menu''' and '''Other Bookmarks''' to see if your bookmarks are there. 3. You can drag these folders to your '''Bookmarks Bar''' folder to see them. To find if any bookmarks are still recoverable: 1. Type in '''about:support''' in the address bar and select '''Open Folder''' under '''Profile Folder''' (not '''Update Folder'''!). 2. There should be a folder named '''bookmarksbackups'''. Open it and find the file modified the most recently. 3. Use a Firefox bookmarks extractor like https://www.jeffersonscher.com/ffu/bookbackreader.html to extract to an HTML file. 4. Open the HTML file in a web browser and check if your bookmarks are there. If so, then you can [[Import Bookmarks from an HTML file|re-import them]]. Otherwise, try Step 3 again with a the next most recent file in Step 2. 5. Note that the folders may be in a different location now. If so, Follow the "To find if your bookmarks are in another location:" at the beginning of this post.
