Provide option to not rely on Google (Analytics)
I don't mind AMR2 sending information to allmangareader.com for statistics, even though I expect some users to mind that. But I very much mind having Google Analytics into a Firefox module. It annoys me already that several websites use that, and maybe I even set up μBlock origin to stop that from happening. μBlock does not filter connections from other modules, so I cannot opt-out myself from the analytics.
The added websites to content_security_policy" are also problematic to me (but I don't think you can not ask for these permissions when some setting is disabled, so that would have to stay I presume).
