Aborting the Tor Launcher setup wizard and restarting should show the language selection dialog again
Aborting the setup wizard does not lead to the language selection dialog showing up again on re-start. I think we should treat it as an integral part of the setup wizard, though, showing it again as well. For instance, it might be the case that users realize they selected the wrong language and try to undo that by clicking on Quit
on the next pane (as there is no Back
button available). But restarting Tor Browser won't help them currently.
