SOMEONE is CONTROLING MY FIREFOX WITHOUT MY PERMISSION!

''Information Your browser is being managed by your organization.'' I am 75 years old. I am RETIRED '''there is NO REASON for an organization to be in CONTROL of ANYTHING on my computer.''' How do I STOP THIS? I don't know if this is related or not, but Something is BLOCKING my ability to use check boxes or circles. Sometimes I can see the box but my response is NOT VISIBLE. Tonight I was trying to complete a survey and the questions were visible but I was COMPLETELY UNABLE to see the answer boxes/circles. Sometimes they would be briefly visible when the page initially opened but QUICKLY DISAPPEARED and were NOT identifiable by manipulating my cursor using mouse, space bar, or tab bar. I have stayed with Firefox as my default browser for several DECADES and PREFER NOT to change now. BUT this MUST STOP!
