Warn the user when they copy a cryptocurrency address from a HTTP Website
If a user copies a cryptocurrency address from a site using HTTP we should:
- Clear the clipboard
- Present a warning (mockup attached)
- Give them the option to reload the page over a new circuit + HTTPS, or perform the copy anyway
Maybe in the future we could also have some sort of reporting mechanism?
This is basically a partial implementation of https://gitweb.torproject.org/tor-browser-spec.git/tree/proposals/ideas/xxx-cryptocurrency-user-safety.txt
