Hi, Why are the minimize, maximize and restore buttons not visible? Sometimes these buttons on the browser window appear, and sometimes all three buttons are not visible. Never had this problem until recent Firefox updates somehow affected this. I cannot tell which update was unaffected since, but this is an ongoing problem and the browser window is blank with no buttons on the top right hand corner. The only solution is to use the file menu and select exit from the list. I may have to open and close Firefox several times until the button icons are visible again. See example screenshots. P.S. I'm using a 32" monitor if this helps.
