I have had a few friend and read a few horror stories Online about people who for one reason or another have lost their Firefox bookmarks and had to start all over. What they were not aware of is that you may not have totally lost your Firefox boomarks at all. There are backups hidden within your PC that I bet you haven’t even checked yet.
First thing you need to do is find your profile folder for Firefox. Depending on your operating system this may be in a different location. If you are unsure, be sure to check out this previous post: Where is my Firefox Profile Folder?
Once you make it in there you should see a folder named “bookmarkbackups”. Double-click that folder, and there you have some of your saved boomkarks that you thought you had lost waiting for you to restore them. To restore your bookmarks, you can launch Firefox, then go to “File” and then “Import”.
Also if you want to live a little more on the dangerous side (first make sure Firefox isn’t running) you could copy one of the bookmark backups, rename it “bookmarks.html” and place it inside of your profile folder replacing the one that is not right. As a bonus, if you need more help on how to backup Firefox using other tools – be sure to check out this previous most wanted post from the Firefox Facts archives.
