Hi stlhseeker, Try this: 3-bar Menu -> Customize at the bottom you will see Toolbars open the menu and select Bookmarks Toolbar Click Done.

Thank you for your fast reply. With just bookmarks tool mark checked I then lose File,Edit View History Bookmarks, Tools Help top left which I don't want to loose. So both Menu Bar & Bookmarks toolbar I have checked. It doesn't solve my problem to have one or the other or both and I am noting an error message once shut down and starting back up that is red across top that says The Bookmarks & History System will not be functional because one of Firefox's files is in use by another application. Some security software can cause this problem.

See:

If you want to have the Menu bar visible then you need to tick that box. Your problem seems to be with the bookmarks not working properly, so both items need to have a checkmark in the setting what toolbars to show to make this work properly once you fixed issues with places.sqlite.

thank you robert, fixed. Mozilla is so hard to use sometimes and 2nd time it has completely disappeared, will see if it stays, thank you again.
