With all due respect, when a user gets an email linking them to a video 
of kittens it doesn't matter one ounce whether you ask them to install a 
plugin or click through a consent dialog on the website itself. They 
will click through anything just so they can get back to watching 
kittens. Do you honestly believe that your typical grandparent will 
benefit from one approach over the other? They're not stupid. They 
simply have better things to do with their time than learning about 
computer security.

Until someone provides us with concrete figures showing that users 
respond to one form of dialog better than another I consider this all 
hearsay. It's silly that people are arguing with such conviction about 
what is more secure when in reality this conversation isn't based on 
facts, it's based on gut feelings. The only fact that we know for sure 
is that users suffer from security warning fatigue.
