Problem #1. The first top bar has a firefox logo at upper left corner and the words "Ask a Question/Mozilla Support-Mozilla Firefox" are on the logo's right side. The first top bar has minimize, overlap and close buttons at the upper right corner. When I click on the logo, a short menu drops from it, which has choices like "restore"..."close". The second top bar has the word "Firefox" at the upper left corner with a downward arrow beside it. They look like white letters contrast to the orange background of a huge button. When I click on it, a double paned menu shows up. It has many choices such as new tab, new private window...bookmarks, history, download...exit. The second top bar also has minimize, overlap and close buttons at the upper right corner, too. There are 7 word titles "file, edit, view, history, bookmarks, tools and help" below that huge orange button at the upper left corner. The logos and the address bar are below the 7 words. I don't need 2 top bars. They occupy too much screen property. Problem #2 The BACK button doesn't light up and cannot work on many web pages. Thank you
