> Right now, after the Cliqz and remotely installed addon controversies, and the fact that Firefox Focus sends analytics data to a third party, I'd say Apple is more privacy focused than Mozilla.

Could you clarify what is the third party that Mozilla is sending analytics to?

Firefox Focus (but not Firefox Klar) sends usage data to Google Analytics.

Mozilla has a promise from Google that Google will not use this data for their own analysis. If you do not trust Google to honor this agreement, Mozilla employees said on a GitHub issue about this, you should stop using Mozilla products.

I am sure the mobile devs will jump in and give an authoritative answer, but you can refuse to send usage data to Mozilla by toggle off in Focus’s settings.

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.

If that is unacceptable in general, then why don't you check the settings of apps before you give them permission to access the internet?

Mozilla is not even sneaky about it. On the Google Play download page, the privacy notice for the app tells you that optional usage tracking is on by dafault. https://support.mozilla.org/en-US/kb/focus#w_privacy

Perhaps you should read the privacy notices for apps if you are concerned? It seems perfectly acceptable to me.
