If your bookmarks have suddenly disappeared, don't worry - you should be able to recover them. This article explains how to get back your bookmarks if they disappeared unexpectedly.

• If you are able to add, delete, and edit your bookmarks but the changes are lost when you restart Firefox, see Can't add, change or save bookmarks - How to fix.

I can see only the default set of bookmarks in the Bookmarks folder

Your bookmarks are associated with the Firefox profile you are using. There may be instances when you or Firefox creates a new profile containing the default set of bookmarks (for example, if you make a separate installation of Firefox or when you downgrade Firefox). A new profile may give you the impression that you have lost your bookmarks.

Determine if Firefox has created a new profile

To see if another profile exists, type about:profiles into the Firefox address bar and press the EnterReturn key. This will open the About Profiles page, which will list at least one profile and could list many. The profile that Firefox is currently using will show: This is the profile in use and it cannot be deleted. If you have another profile listed, you can launch that profile in a new Firefox browser window to see if it contains your lost bookmarks. See Recover user data missing after Firefox update for more information.

My Bookmarks Toolbar is missing

If you were using the Bookmarks Toolbar for quick access to your favorite bookmarks and the toolbar is now missing, you may have turned off the option to display the Bookmarks Toolbar. To turn it back on:

For more information, see the Bookmarks Toolbar - Display your favorite websites at the top of the Firefox window article.

I can't find all of my bookmarks and folders

You can view all of your bookmarks and folders when you click the Bookmarks menu item in the Firefox Menu bar, if you enable the Menu bar. You can also add a Bookmarks menu button to your Firefox toolbar, a button that with a click, shows all of your bookmarks and folders. Follow these steps:

1. Click the menu button , then click More tools and select Customize Toolbar…
2. Drag the Bookmarks Menu button from the Customize Firefox tab onto the toolbar.

My bookmarks have disappeared

Firefox automatically backs up your bookmarks and saves up to 15 backups in the profile bookmarkbackups folder. To recover bookmarks that were previously saved in the Bookmarks menu or on the Bookmarks toolbar but are now missing, you can restore them from one of these backups:

1. Click the menu button to open the menu panel. Click Bookmarks and then click the Manage bookmarks bar at the bottom.
2. In the Library window, click the Import and Backup button and then select Restore.
3. Select the backup you want to restore from the list of dated automatic backups.
   • You can also select Choose File… to restore bookmarks from a manual backup, if you created one.
4. After confirming your choice, the bookmarks from the backup you selected will be restored.

For more information, see Restore bookmarks from backup or move them to another computer.

There is an "Old Firefox Data" folder on my desktop

In some cases, Firefox may create a folder on your desktop called "Old Firefox Data". This folder contains a complete backup of your Firefox profile and can be used to restore bookmarks and other missing information. If you have this folder on your desktop, see Recover important data from an old profile.

I can't find my bookmarks after importing them

If you imported your bookmarks from another browser, you can find them inside a specially-named folder, for example, From Google Chrome or From Microsoft Edge depending on the browser, in one of these locations:

• At the end of the Firefox Bookmarks Toolbar.
• At the bottom of the Bookmarks list accessible from the Bookmarks Menu toolbar button.
• In the Bookmarks Library. To open the Bookmarks Library window: Click the menu button to open the menu panel. Click Bookmarks and then click the Manage bookmarks bar at the bottom.

If your source bookmarks were stored in a hierarchy of folders, the folder structure is preserved inside the specially-named folder. If desired, you can move your imported bookmarks to other folders. See Bookmarks in Firefox to learn more about organizing your bookmarks.
