Thanks Kevin and Gunner for going through this idea. I have been
thinking about this lately and I have decided to share a few points.

When we started doing the Tor styleguide we thought a lot about how to
design things in a way that could be Tor and privacy friendly over all.
version in order to guarantee an almost seamless experience between the
two. But this is not the only thing that makes a website Privacy
friendly, and noticing you have a few open questions in the pad, I will
try to add a few more ideas.
Things that are bound to break the design are certainly the following:
- Importing styles (CSS) and fonts from third parties (like google fonts
and other cdn)
- Embedding content from third parties (like media and videos, but also
page previews) - Maybe content can be processed server-side first or
- PDFs (/me thinks) could be generally considered ok if can be opened
within the Tor browser reader
- Do not ask to share location
- Canvas is ok if implemented properly (I have seen your points on the
pad), but personally I would avoiding it. My take is that anything that
should ask for consent is generally a bad practice.
I have seen you mention that vector images do not render (SVG), so the
appropriate media queries and image qualities should be used instead -
maybe this is actually something we could implement in our styleguide
and could benefit other people directly.
Another thing that could be considered is that we (tor, tails, a few
other orgs) do not log IPs nor User Agent infos. There have been a few
projects started regarding privacy friendly logs. This could be
something worth exploring again. Also some don't even understand the
rationale behind this. A related project could be about privacy-friendly
web analytics. Some install and use Matomo (https://matomo.org/) but it
is worth mentioning that if you log anything you will end up with a lot
of user data.
One more interesting point is that, because of the GDPR, some website
have been offering a text only version and some people have been doing
performance measurements of these lean pages. The results are amazing,
some news site have been reduced from approx 5MB to 500KB or less.
A follow up to this - a bit of a stretch maybe - could be trying to
involve an audience that wouldn't even consider all these points when
developing a website, by evaluating common JS libraries and framework to
see how they perform.
I think this effort could also be a practical way for people to
understand how Tor can protect them on the web. An example is this
article about link shims and privacy badger
This is already blocked by Tor browser in high security mode.
