It sounds like the folders all got "collapsed" and need to be expanded again. You can click the > icon to the left of the folder name to open it and show its contents, and similarly with subfolders. Does that work on yours?

Here's a screenshot of what I'm talking about, since a picture may be worth 1000 words in this case:

In your screenshot you have the "twisty controls" next to the three options. When I click on the book mark star I get the three options but no twisty.

Thanks for the try though.

Could you try double-clicking the top-level category names to expand them? (That doesn't work with rename-able folders; double-clicking those opens a field to edit the name.)

When I double click bookmarks menu I get the folders dropping down but not the bookmarks below the folder list that aren't in a folder.

Firefox only displays folders in that dialog because it's a folder chooser (for where you want the current page's bookmark saved). The bookmark will be placed at the end of whatever folder you choose.

In case it's of interest:

Firefox 57+ has an optional bookmarks menu button () you can add to the toolbar. Either:

(A) Use the Customize panel (Customize Firefox controls, buttons and toolbars) to drag the icon to the desired spot on the toolbar

(B) Use the method from Bookmarks in Firefox - section entitled: How do I add the Bookmarks Menu button to the toolbar?

• Click the "Library" button:
• Click "Bookmarks"
• Click "Bookmarking Tools"
• Click "Add Bookmarks Menu to Toolbar"
