I would sure be interested in your method of running firefox on stretch, 
without using extensions or addons from outside the debian repositories?

I never mentioned jessie, not sure what the reference is about?  My point 
was that is ff needs extensions to be "secure" or reliable, and if the 
only place to get them is from outside the debian repo, then logically, 
the pkg belongs in "contrib" or plain kicked out of the repo.
