i'm running pdf-based exhibit on public touchscreen , don't want users able execute of floating toolbar options (print, save, exit read mode). using url parameters (toolbar=0, navpanes=0,etc.), putting browser in kiosk mode, , disabling read mode in reader preferences work…until don't. let me explain: because pdf links html page (which iframes pdf), going , forth between pdf , html inevitably causes floating toolbar reappear. i've given on ever getting rid of floating toolbar. if that' off table, want thwart toolbar's functionality. so, when user clicks on symbol exit, don't crash kiosk/full screen mode. [note: previous similar exchange on didn't answer me, since effect of disabling read mode isn't persistent when user moves pdf html , back-again: can hide adobe floating toolbar when showing pdf in browser?
