Tor: The second generation onion router – annotated version

Sadly, I don't think we will witness a working implementation of Hornet anytime soon. Hornet was designed to be implemented at the core Internet infrastructure in order to operate at the network level. It is practically -impossible- to achieve this level of migration (remember IPv6). Moreover, it requires the deployment of a PKI on an unprecedented scale, which may or may not be secure. However, it's true that some ideas might be extracted and used in other future projects.

Same on FF44.

Nice intended but in the end very annoying reader.

and also for firefox on linux (centos7)

But this is only the case when you connect to non .onion site, right?

I see you're running Gnome.

Wrong. The exit-node might control the traffic but that does not know where you came from. You need to watch the connection into the torrnetwork as well.

When you connect to https its pretty hard and risky for the exit node. If the user uses https with pinning its even harder and more risky.

The Tor Network is not perfect, nothing is in this space. So you need to make a more detailed analysis then yours to evaluate it.
