[https://support.mozilla.org/en-US/questions/1300502 This thread] was not resolved and sould not have been closed. No adequate solutions, remedies, or promises for fixes were provided. No valid argument for not providing such was given. Please re-open. It is the nature of mobile apps that users can only choose between the latest vesion and whatever version they currently have. When they allow the update they may regret it. It is actually quite troublesome to reinstall an older version of an app; on Android with an APK it is possible; but, quite frankly, users should be able to control which versions of apps are installed on their devices. GAFAM, of course, have no interest in allowing this. Please roll-back Fenix from the main stream until it is actually ready for release, or risk making a thin user base even thinner.
