Completely lost control of Firefox
Firefox has gone mad. Have refreshed. Cannot control screen layout. I want the sidebar option for bookmarks. Have dragged what I want into the option box and pressed button 'Done'. Nothing happens. I have now lost all the bars.
Have used Firefox happily for about 15 years, but now it looks as if I will havve to abandon it for a less good browser.
