how can i expand the view of my bookmarks?
At this point I can only get a list of my bookmarks to the left of my screen by clicking on the "open book" icon in the upper right corner of the screen between "view history, saved bookmarks...... and "Firefox Account". There used to be a way that I could get a full screen listing of my bookmarks including their complete URL name. Has that option been removed???

That is likely the Bookmarks Manager (Library; Win:Crtl+Shift+B; Mac:Cmd+Shift+B; Linux:Ctrl+Shift+O).
See also Bookmarks -> Show All Bookmarks.
- you can tap the Alt key or press the F10 key to show the hidden Menu Bar temporarily

You can optionally add the "Bookmarks Menu" button that shows the bookmarks in a drop-down list and a link to open the Library to the Navigation Toolbar via these steps:
- click the bookshelf
icon on the Navigation Toolbar or alternatively use the Library menu in the "3-bar" Firefox menu button 
drop-down list
- click Bookmarks
- click "Bookmarking Tools", then click "Add Bookmarks Menu to Toolbar"
should appear on the Navigation Toolbar.
You can also drag the Bookmarks Menu button from the Customize palette to the Navigation Toolbar
