Also, (separate problem) when I displayed screenshots, it went full-screen with no way I knew to exit except killing firefox process. May be a firefox problem and/or my lack of knowledge. I couldn't find any menu choice nor right or left click menu that worked. Sometimes the address line could not be edited.
