 Our first party isolation patches are activated right now (ESR 45 based
 Tor Browser) if the checkbox "Restrict third party cookies and other
 tracking data" is checked. But that's not the case anymore with an ESR 52
 base. We should fix that or remove that checkbox altogether.

 It might be a sign, though, that some of our first-party isolation code is
 not working. We should doublecheck that that's not the case
