There are many ways to access your Bookmarks. For example:

Top Menu Bar

To display the classic File, Edit, View... bar, use the Toolbar list to turn it on. See: Restore the Menu bar in Firefox.

Bookmarks Menu button for the toolbar

There is an optional bookmarks menu button () you can add to the toolbar using the Customize panel (Customize Firefox controls, buttons and toolbars).

Bookmarks Sidebar

You can use the Ctrl+B keyboard shortcut to open/close the Bookmarks Sidebar for when you prefer a list that stays open and doesn't disappear when you click away. More info: Use the Firefox Sidebar to access bookmarks, history and synced tabs.

Do any of those work for you?

Yes. I am an old fart that has a lot of trouble with computers. But if all I have to do is hit control B the bookmarks come up on the left which I like better anyway. And I can now see all my bookmarks.

Thanks. Sometimes I wish Firefox wouldn't change things on me but its still the best. Especially with help like you.

Compared to people who post here every couple months, I think you're doing well.

Also, I forgot this in the earlier reply:

Bookmarks Toolbar

The Bookmarks Toolbar can appear horizontally below the address bar, but shows a different group of bookmarks from the main Bookmarks Menu. More info on this bar: Bookmarks Toolbar - Display your favorite websites at the top of the Firefox window.
