I accidentally cleaned Firefox bookmarks!

As a CCleaner user of many years, I’m really upset to find myself having GREAT difficulty using the latest version. It’s taken me a long time to even get the app running on my laptop and now I find I accidentally lost all of my Internet bookmarks in Firefox. I was trying to specify exactly what I wanted to be cleaned, which was very easy in the old format but is opaque in Version 7. Is it possible to get my bookmarks back? It’s scarey to thin what else I accidentally had CCleaner erase. I’d be very grateful if someone can help me with this problem.

Hi NicolaB:

See the Firefox support article Recover Lost or Missing Bookmarks. As noted in that article, Firefox automatically creates a backup of your bookmarks every few days and saves up to 15 of these backups in your Firefox user profile.

If you go to Bookmarks | Manage Bookmarks | Import and Backup | Restore this should display a list of recent bookmark backups - see my image below. Select the most recent backup [or in your case, the last (largest) bookmark backup created just before you accidentally deleted your bookmarks with CCleaner 7] to start the restore.

If your list of bookmark backups is empty then that means CCleaner 7 has, unfortunately, also wiped your bookmark backups. If that is the case post back and let us know, since there might be another way to recover at least some of your bookmarks from an older Firefox profile.

Also let us know if you use another browser like Chrome or MS Edge on a regular basis, since you also have the option of importing bookmarks from another browser into Firefox.

HINT: Every week or so I manually back up my Firefox bookmarks (Bookmarks | Manage Bookmarks | Import and Backup | Backup) and save the .json file this creates to a removable USB stick. That way if some disaster happens and all the bookmark backups Firefox has automatically saved on my hard drive are lost I can go to Bookmarks | Manage Bookmarks | Import & Backup | Restore | Choose File and restore my bookmarks from that removable USB stick.
