All my other applications and browser apps show a "toolbar", the uppermost edge of my screen, with "Firefox" and bookmarks, etc. It is just gone. I can't figure out why it is not showing up or available. I am not in full screen mode, although that hides the bar on top also. Mac OS 10.11.6, preferences says latest available update, although I cant tell because I can't set the "About" Firefox button.

Firefox 78.15.0 is the last version for your Mac OS X 10.11 platform (mozilla-mac-eol-esr1), so you will no longer receive updates.


Do you see any of the toolbars like the Navigation Toolbar with the location bar or the Tab bar?

Can you attach a screenshot?


Try to rename/remove xulstore.json in the Firefox profile folder with Firefox closed.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).

Location used for the main profile that keeps your personal data (Root Directory on about:profiles).

  • ~/Library/Application Support/Firefox/Profiles/<profile>

In Mac OS X v10.7 and later, the "~/Library" folder in the Home directory is a hidden folder.

Deleting the xulstore.json worked.
