* see above.
* `extensions.pocket.enabled` to `false` so the Pocket integration goes away
* `network.security.esni.enabled` to `true` in order to enable encrypted SNI.
* Requires DoH, see the next section!
@ -48,13 +49,29 @@ redirect_from:
* `network.trr.bootstrapAddress` DNS server to use for resolving the DoH
name, e.g. `84.200.70.40` (Resolver 2 of [DNS.watch](https://dns.watch/)
in Germany)
* `network.trr.mode` 3 to enforce DoH which is [required by Firefox ESNI](https://bugzilla.mozilla.org/show_bug.cgi?id=1500289)
in Germany) or `149.112.112.112` (Resolver 2 of [Quad9](https://quad9.net))
* `network.trr.mode` 2 to prefer DoH, but fallback to system resolver (or 3 to enforce DoH without fallback)
* [DoH is required by Firefox ESNI support](https://bugzilla.mozilla.org/show_bug.cgi?id=1500289) which encrypts SNI which would still leak which
sites you visit.
* I have ended up to recommending 2 as otherwise the DoH server going
down stops DNS from working on your Firefox entirely, which may be
more of a problem than unencrypted SNI as not everyone supports it.
* `network.trr.early-AAAA` `true` to hopefully prefer IPv6
* `network.trr.uri` for the actual resolver address, e.g.
`https://mozilla.cloudflare-dns.com/dns-query` or
`https://mozilla.cloudflare-dns.com/dns-query` or `https://dns.quad9.net/dns-query` or
[check curl wiki](https://github.com/curl/curl/wiki/DNS-over-HTTPS#publicly-available-servers)
Some notes:
* You can confirm TRR working by visiting `about:networking#dns` where
you should be seeing DNS cache of Firefox and a lot of `TRR: true`.
* Quad9 became my preferred resolver through anxiety about other options
being small (and possibly more likely to go down) or commercial while
Quad9 is non-profit organization and 2019-03-20 apparently the default
fallback resolver of dnscrypt-proxy (at least in Debian).
* Quad9 while having filtering of malicious domains should be easy to figure
out as the problem if something doesn't work on my computers as due to the
previously mentioned bug I am mainly using it on Firefox.
