Well said. May be worth reading through this GitHub issue and this Bugzilla issue as well. Its worth noting its also directly integrated into the browser as well in about:addons.

I'm personally not a fan of Firefox/Mozilla integrating and using Google Analytics, even under these circumstances, and think it does deserve criticism, but it is what it is I guess. I do hope they switch to a better alternative in the future.

In the meantime, setting the following about:config options should take care of and fully strip out Google Analytics and extension recommendations from about:addons:

"extensions.getAddons.showPane" to false

"extensions.htmlaboutaddons.recommendations.enabled" to false

"browser.discovery.enabled" to false

"browser.discovery.sites" to be empty
