The field where the url should be visible, has shrunk so that I cannot see the url. I want to restore that field so that I can see the entire url.
Until a few days ago, I was able to read any reasonably short url in the familiar field or space at the top of the Firefox screen. Suddenly, that field, I mean the space where I might type a url, has shrunk. How can I restore that field? And incidentally what is that field called? Is it the address bar or the navigation bar or what?
