The usage data is not sent to Mozilla but to a marketing company called "Adjust Inc.": https://github.com/mozilla-mobile/focus-ios/wiki/Install-Tra...

Firefox sending my data to a marketing company should not be on by default... Heck, it should not even be an option.

Usage data isn't much of a privacy issue, but if you are a concerned user, don't you already have the habit of going through the settings of each new app? I found this one 2 minutes after installing and though nothing more of it.

By the time I have disabled it they have already pinged the "Adjust, Inc." servers at least once with my information. That's unacceptable.
