Comment (by mcs):
Here are the items that Kathy and I found for Firefox 52:
a) As I mentioned in comment:4, captive portal detection is enabled in
FF52. It won't be useful over Tor, so we should disable it via `network
.captive-portal-service.enabled = false`. I thought we already had a
ticket for this, but I cannot find it.

b) MediaError has gained a message property that may include system
diagnostic
information. We should make sure it does not provide fingerprintable
information
about the user's computer.

c) Kathy and I don't fully understand what was done in the following bug
and
how it affects our use of the --disable-eme configure flag:
https://bugzilla.mozilla.org/show_bug.cgi?id=1300654
Maybe the difference is that now the framework that supports EME is always
built and --disable-eme only skips building the bundled providers?
d) The CustomElementRegistry.get() method of the Web Components API has
been implemented. It looks like all of the custom element features are
disabled via `dom.webcomponents.customelements.enabled = false`, but
eventually we should make sure that these APIs do not introduce any
linkability problems

e) A note related to e10s: use of accessibility tools is no longer a
reason to disable e10s (it was for Firefox 48-51, as I noted in
comment:11):
