0390: better reference

- EFF has pretty pictures and stuff and explains the issues (replaces wikipedia which people can still search for)
- tor issue doesn't hold anything important (out it goes)
- moz wiki page I'll leave in for the bugzilla links if someone wants to research how it's all meant to work
