Also important: can you choose what to allow to pass through your connection? Can I rule out the case of someone accessing a child porn site through my connection?
If I were to run such a proxy, I'd only allow HTTPS or ssh traffic that I cannot possibly decrypt even if I wanted to, so I can't be held accountable for what I proxy.
Same is probably true for the other end: if I were to rely on someone unknown out there proxying my connection, I'd strongly prefer my entire connection to be encrypted, and my identity hard to trace. Else my proxying peers might happen to be exactly the people I'm trying to hide from.
Yes.

It doesn't appear that you can, but don't proxy for people you don't know, then. How on earth do you propose ruling "out the case of someone accessing a child porn site through my connection?" anyways?
As for the rest, it appears to just be a browser extension that proxies your connection, whether HTTPS or no. If you want to ensure that you're only going over HTTPS, install something like HTTPS Everywhere or block all connections that aren't secure.
This is like a VPN service but decentralized, with all the downsides that brings (have to find a peer, trust the peer, etc). It is not Tor, not a replacement for secure connections to sites, etc
This is a peer-to-peer proxy so you don't have to proxy with a friend in the USA.
uProxy should be equally useful in avoiding US secret services (though Google's site doesn't highlight this use case).
