 > We don't want to have a `ResistFingerprinting`-check here? What makes
 that feature different from, say, the one in #10286 where you explicitly
 added one? Or maybe that's just because the other timestamp clamping code
 does not have such a check either?

 Yes, I left it out to be consistent with the other clamping code we
 currently have in Tor Browser. Once it gets uplifted to Mozilla, we can
 put it behind a pref. Jonathan has already created infrastructure for that
 in https://bugzilla.mozilla.org/show_bug.cgi?id=1217238
