Comment (by rollback-question):

 thank you very much for looking into it! here are the app.update prefs:

 TBB 1 (broken one)

 user_pref("app.update.download.attempts", 0);
 user_pref("app.update.elevate.attempts", 0);
 user_pref("app.update.lastUpdateTime.addon-background-update-timer",
 1558952020);
 user_pref("app.update.lastUpdateTime.background-update-timer",
 1558951540);
 user_pref("app.update.lastUpdateTime.blocklist-background-update-timer",
 1558951780);
 user_pref("app.update.lastUpdateTime.browser-cleanup-thumbnails",
 1558470262);
 user_pref("app.update.lastUpdateTime.experiments-update-timer",
 1558951900);
 user_pref("app.update.lastUpdateTime.search-engine-update-timer",
 1558951660);
 user_pref("app.update.lastUpdateTime.xpi-signature-verification",
 1558952140);
 user_pref("app.update.log", true);
 user_pref("app.update.postupdate", true);


 TBB 2 (working one)

 user_pref("app.update.download.attempts", 0);
 user_pref("app.update.elevate.attempts", 0);
 user_pref("app.update.lastUpdateTime.addon-background-update-timer",
 1558913305);
 user_pref("app.update.lastUpdateTime.background-update-timer",
 1558715487);
 user_pref("app.update.lastUpdateTime.blocklist-background-update-timer",
 1558913425);
 user_pref("app.update.lastUpdateTime.browser-cleanup-thumbnails",
 1558913065);
 user_pref("app.update.lastUpdateTime.experiments-update-timer",
 1558913545);
 user_pref("app.update.lastUpdateTime.search-engine-update-timer",
 1558913185);
 user_pref("app.update.lastUpdateTime.xpi-signature-verification",
 1558913428);


 after moving the directories away and starting the TBB 1 again nothing
 changed, i saw in the "about" window that a download was triggered but it
 lasted only a few seconds. then the bubtton to restart the tor browser
 appeared and it started all over again, still based on Firefox 60.6.1esr
 and showing the button to restart the tor browser every time i restart it
