'''Step 1: Check for Bookmarks Backup''' Firefox automatically creates backups of your bookmarks. You can restore them using the following steps: Open Firefox. Click on the menu button (three horizontal lines) in the top right corner. Select Library (or Bookmarks). Click on Show All Bookmarks (or Manage Bookmarks). In the Library window, click on the Import and Backup button at the top. Select Restore from the dropdown menu. You will see a list of backup dates. Choose a date before you refreshed Firefox to restore your bookmarks. '''Step 2: Check the Bookmarks Menu''' Sometimes, bookmarks may not appear in the usual places after a refresh. Check the Bookmarks Menu and Other Bookmarks folder to see if they are there. '''Step 3: Check for Other Profiles''' If you have multiple profiles in Firefox, your bookmarks might be in a different profile. You can check this by typing about:profiles in the address bar and seeing if there are other profiles listed. '''Step 4: Manual Recovery from Backup Files''' If the above steps do not work, you can manually recover bookmarks from the backup files: Navigate to the Firefox profile folder: Press Windows + R to open the Run dialog. Type %APPDATA%\Mozilla\Firefox\Profiles\ and press Enter. Open the folder corresponding to your profile (it will have a name like xxxxxxxx.default-release). Look for a folder named bookmarkbackups.
