Dougie explained this to me earlier on today and we both think there's still an outside chance that your bookmarks are intact.
Try the following...
Open your Waterfox browser...
1. At the top of your screen left click on "
Bookmarks". (Between History & Tools)
2. Left click on "
Show All Bookmarks".
3. Left click on the "
Import and Backup" tab.
4. From the drop down menu move your cursor onto (hover) "
Restore".
If you still have your bookmarks you will see a list like the image below. Your dates may be different than the pic.
If you do see a list, then go to step 5.
If you don't see anything in that menu...Then sadly you've lost your bookmarks for good......
5. Left click on the entry at the top of the list.
6. Click "
OK" in the box that appears.
7. Close the window and restart the Waterfox browser.
Hope this works out for you...
