Hi henry4004, There have been some changes to the UI recently. Everything is still there, just in a slightly different location. Do you have the ''Firefox'' menu in the upper left hand corner? If you do, try hitting ''Alt'' to temporarily show those menu items. If you want those items back permanently, you can go to ''Firefox > Options'' and turn on the ''Menu bar''.
