I agree to some extent, e.g. the pocket integration and Mozilla burning cash on things that aren't related to Firefox, but Chrome's decision to limit/break key adblocking APIs across their whole ecosystem is much worse. I'd be willing to ignore almost any number of removed extensions to continue using a browser that's not owned by a glorified adtech company.
Browser extensions are going to be turned into a web standard, and W3C is controlled by Google, so Firefox will probably lose its adblocking API: http://browserext.github.io/
