With the latest update when I open a FF browser window the title bar does not have the 3 icon for Shrink. Resize of Close. To get these to appear I much click on the tab for the window on my Taskbar to make the browser window close and then click again to reopen it at which time those 3 control are back where they should be.

Why is this happening after using the browser for many many years? This is really annoying and I do not understand what you all did to mess things up or if i can fix in on my end.
