Why do we encourage users to override security protections? I click &quot;get started now&quot;, and am presented with a warning message reminiscent of an ssl cert error. In general when users see the &quot;this site is trying to install software&quot; warning message  I hope they become suspicious and do something else (certainly not override the warning dialog). I am not entirely sure why that should not be the case now. I am inclined to think that mozilla is an organization with &quot;good&quot; technology and principles.  But if that is the case why cant they get the left hand to talk to the right hand and install test pilot in a manner that does not teach users that its okay to override the security warning dialogs?
