That all sounds odd. Why was "Always use private browsing mode" in
 about:preferences checked? Was that deliberate?

Does it block sites if the user deselects "allow to run in private
 windows" in the addon and then puts Firefox in Private Browsing
 mode?

And in answer to your original question - how to stop the use
 changing the options for an addon - I don't know of a way. You
 could ask the addon author.
