 Replying to [comment:13 rollback-question]:
 > i found a difference between them,

 now on version 8.5 but based on firefox version 60.6.1esr - it shows a
 "Restart to update Tor Browser" button, when pressed the tor browser gets
 restarted but with the same version and still showing the same button
 again

 Huh, yes. That looks broken. You should not be on Tor Browser 8.5 and
 Firefox 60.6.1esr at the same time. If you open `about:config` and set
 `app.update.log` to `true` and check your browser console (Ctrl+Shift+J)
 while doing the update are there any error messages showing up that could
 give some clues about what is going on?

 > the second TBB i upgraded that recovers the tabs without problem (right
 screenshor) is on version 8.5 but based on firefox version 60.7.0esr and
 doesn't show any button and works fine

 That's the expected behavior.
