First of all I use a Macintosh! So please submit your assistance based on this fact. As previous answers did not. In Firefax, I lose the Address Field. Why?
First of all, I use a Macintosh! All previous attempts to answer my problem were addressed to that other computer medium, Windows. I apologize for this. For whatever reason, I lose the Address Field when I pull up Firefox, that blank space awaiting my entry of some web site I want to visit. It's just not there. I go through the Preferences, etc, and cannot retrieve it, although I have done so in the past but God knows how. Thank you all.
