I turned on my MAC os Sierra 10.12.1. Mozilla Firefox was missing. I downloaded it again. My bookmarks, favorites, & yahoo toolbar was missing. How do I retrieve?

Hi, first try restarting Firefox - 3-bar menu > Exit Firefox in bottom right corner.

If that doesn't help, and in case a Refresh has occurred, please look on your Desktop for a file named Old Firefox Data - Refresh Firefox - reset add-ons and settings.

If the file isn't there, for bookmarks only, you can try this: Open bookmarks > Show All Bookmarks > Import and Backup > Restore, and see if you have a backup there.

If not and for other data, please see -
