1. Press Windows + R, type cmd and click OK. Or you can also type cmd in the Windows search bar. 2. Open Command Prompt, type ipconfig /displaydns, and press Enter. Now, you can see the recently visited websites. You can view, copy & paste the important websites into Firefox, and save them as bookmarks.

Restore Firefox history with DNS cache

Solution appears to be outdated I have windows 10 and the latest version of Mozilla-Firefox. Page says "1. Click "Start" > "Search" > "Tools" > "Folder Options." Start what? Then it says "Search" Search... Search Where? Tools... What tools I have tools all through the computer. THEN ... 2. Click "View" > select "Show hidden files and folders" > uncheck "Hide extensions for known file types" and "Hide protected operating system files". after trial and error I found a file and was able to click on show hidden files, but there is no option to "uncheck "Hide extensions for known file types" and "Hide protected operating system files" so its a dead end cant find what they said, how they said.
