I'm having a hard time being mad at Mozilla for this kind of thing. Which privacy minded person installs an application and doesn't go through the settings to find all of the privacy minded features and disables those they don't agree with? Do we not "Trust but verify" all the things because of these kinds of options that pop up? Who is at fault here, the application or the user?
We, as users, need to start taking our own settings on our systems more seriously and stop dumping all of our responsibility into the hands of someone else. Go through the settings of your apps. Save them so you can get to them when needed. Disable everything you can or want. Don't trust it until you've done the necessary research and tested it for yourself.
