Sorry , typo....I need to know how to track even though the privacy browser ? Question#2 how do I get rid of the privacy browser option ?

So you want to disable private browsing, I dont think a addon is made for android yet, but there is one for desktop firefox.

There is nothing reliable to disable private browsing. You are better off installing a content monitoring filter on your computer, to be able to either block websites or track what sites are visited.
