 Based on https://bugzilla.mozilla.org/show_bug.cgi?id=1401493 I ran some
 tests (Windows). The platform difference was already noted. Note: this is
 not (for me at least) about blending TB users with FF RFP users, but
 ultimately about making sure that Tor Uplift patches came thru unscathed
 (and that includes relaxing prefs used in the past or still used in v8*
 that are now covered by RFP)

 Anyway, just FYI, if you didn't want to wait until the next ESR cycle,
 standardizing the buildId could be a good patch to backport: hardcoding
 `20181001000000` rather than relying on a pref and using `20100101`. - see
 https://bugzilla.mozilla.org/show_bug.cgi?id=583181

 Up to you guys :) Not backporting it doesn't harm Tor Browser's FP'ing
 entropy
