Option to disable/block Google Analytics in "about:addons"

[CryptGoat]

Mozilla is using Google Analytics in the "about:addons" page and unwilling to remove it, even the Tor Browser is affected: mozilla/addons#3145

I would love to seen an option in Privacy Settings to disable this third party tracking. Enabling Do not Track is supposed to disable this behaviour in a future release of Firefox: mozilla/addons-frontend#2794

Users should be protected from this kind of "internal" tracking without having to enable DNT.

To be clear we will be removing GA when Do Not Track is enabled, and this will not require an update to the browser. Because the content that loads GA is technically a web page (at https://discovery.addons.mozilla.org) we should be shipping a fix that disables Google Analytics when DNT is enabled. This will be automatically rolled out in browsers.

Using a browser preference to enable this preference, as I've mentioned would require changing Firefox code to expose that setting and would take many months to roll out to users.

Arguably DNT is the right setting here as technically the Discovery Pane in about:addons is a remote web page (it's loaded in an iFrame), so I think a new setting is unneeded. But that's just my personal take, not speaking for Mozilla on that point 😄
