The first point there is changing the API for their add-ons, which they did for performance, maintainability, and security reasons. No dark pattern there.
On Firefox Suggest (points 2 and 3), are you saying it is a dark pattern because their messaging when you enable the feature is not clear about what's happening? What's wrong with the messaging and how would you like it to be better?
With ads on the new tab page, I don't see what is a dark pattern about it? Or are you just saying that you don't like ads and wish Firefox would find another source of revenue?
With the Mr. Robot extension (points 5 and 6), I think it was a dumb choice, but again I don't see how it's a dark pattern?
