Hi,

If you can't find all of your bookmarks and bookmark folders after updating to the new Firefox Quantum (version 57), try this solution:

1. Click on the Library icon on your Firefox toolbar.
2. Click on Bookmarks, then click on Bookmarking Tools.
3. Click on Add Bookmarks Menu to the Toolbar.
   • A Bookmarks Menu icon will be added to your toolbar.
4. Click on the new Bookmarks Menu icon. You should get the same Bookmarks Menu as in earlier Firefox versions.
5. Alternatively, click on the Sidebar button and Select Bookmarks.

Let us know if this solves the problem.

• For other ways to customize Firefox, see Customize Firefox controls, buttons and toolbars.
• To learn more about Firefox bookmarks, see Bookmarks in Firefox.

Also, the left side panel is called the Sidebar. You can open the Bookmarks Sidebar from a dedicated Sidebars button, or using the keyboard shortcut Ctrl+b. (Note that some websites might intercept Ctrl+b for other purposes, such as turning bold on and off in an editor.)
