Backing up and restoring your bookmarks in Firefox is a pretty easy thing to do. However, did you know that Firefox has a way you can rollback to a previous day’s bookmark backup? This can save you a lot of heartache if you have accidently deleted a folder of useful bookmarks and you need to get them back in a hurry.
The first thing you will want to do is open up the Bookmark Library, by going to Bookmarks > Organize Bookmarks in Firefox’s menu toolbar. You can also press Ctrl+Shift+B to bring it up too.
Next, click on Import and Backup. Move the mouse down to where it says "Restore" and you will see the collection of bookmark backups the Firefox has stored locally for you. To roll your bookmarks back to one of these days, simply select the date you want to roll back to.
Now, the next time you are in a pinch with your bookmarks – and you need to quickly restore thing to the way they were, you can do so with this quick bookmark restoring tip.
