In the past week, I have noticed a change in my Mozilla Firefox browser, and I don't like it one bit! There is no "back" button or tab in the upper left where it always is on all browsers. I don't have an address bar, where I can enter my own "www." web address. I also had a "last Pass" password application that showed in the upper toolbar area, which allowed me to open favorites without manually entering the various passwords; that has disappeared. Why has this stuff gone away? What's up? I don't want to be limited by these, and other changes.
