The fact that a Mozilla product sends my data, even if it is only my IP address, to a third party, is a disgrace. I don't really care what the data is.

I understand they need analytics and telemetry. They have the money, they have the power to build all of those in house. They should not be sending my data to a third party, whatever that data might be. That's all. I expected better from Mozilla. Pocket integration was a letdown, this is even worse.

You can disable data collection in the settings, or directly install Firefox Klar, a special version of Firefox Focus without telemetry made for Germany, Austria and Switzerland.

only 3 country care about privacy?

Yes, unfortunately. In these countries, the IP address is considered private information. For Android, the app is available in F-Droid.

Klar is only available in those stores, but not worldwide.

Then disable telemetry, it's exactly the same thing.

Klar is available worldwide on F-Droid.

I don't use Android. I don't understand why did Mozilla add Klar to the stores of those countries only.

As others have said, the option to disable telemetry is in the other stores.

Read the article, it says it too:

==================

You can turn off the anonymous data collecting of Firefox Focus by tapping on the settings icon, and flipping the switch next to "send anonymous usage data" to off.

==================

You should stop using the internet if you're concerned about other people knowing your IP address.
