Since version 8.0 of Foxit PhantomPDF/Foxit Reader, you are able to open all PDF files with navigation panels hidden by doing as follows:
1. Go to "File"menu in Foxit PhantomPDF/Foxit Reader > "Preferences" > "History" > uncheck"Restore last view settings when reopening" > click"OK"to save the setting.
2. Open any PDF file, press"F4" in Foxit PhantomPDF/Foxit Reader to hide the navigation panels. Then all of other PDF files that you open next time will be opened with navigation panels hidden.
Note: F4 is not supported in Foxit Reader for Linux. You may go to View > Navigation Panels >uncheck all the options there.
