On the new Firefox version cannot find 'close tab'; have to exit out of the entire Firefox. Somehow, I lost this feature.
May have several pages open and those are noted in the toolbar. However, cannot exit a page without exiting Firefox. Cannot locate the 'close tab' which used to be under the 'File' tab at the top.

try to close tab with ctrl + F4 / strg +F4
You can right-click the Tab you want to close and select Close Tab.
Or, you can Middle-click a Tab to close that Tab.
Or, you can hit Alt, then F, then C to close the Tab that is showing, from the keyboard.
Some menu entries in the main menu bar are hidden if you use the mouse and only appear if you use the keyboard to open the menu (Bug 626825).
You can see the difference if you use Alt+F to open the File menu or Alt+B to open the Bookmarks menu and compare that to what you see if you use the mouse to open the menu after you have made the menu bar visible by tapping Alt or by pressing F10.
