Consider resetting security.enable_tls_session_tickets
Taking a look at #28746 (moved) I realized torbutton_update_isolation_prefs()
still sets security.enable_tls_session_tickets = !isolate
. This should have been removed in #17252 (moved). For users which never played with privacy.firstparty.isolate
this will still have the default value, but at least in my browser tls session tickets were disabled. I guess it might be the same for other developers/advanced users.
I don't see a way of knowing whether security.enable_tls_session_tickets = false
was set manually by the user or by torbutton
. But I think we should consider resetting the pref to the default value to enable tls session tickets for all users.
