I2P In Private Browsing EN

i2psetproxy.js

This is an Experimental webextension which introduces a set of new "Private
Browsing" modes to Firefox-based browsers(Supporting webextensions) that makes
it easier to configure a browser to use I2P securely and adds features for
making I2P applications easier to use. It does this by isolating I2P-specific
settings to Contextual Identities within Firefox, then loading them
automatically when the user requests them. It also adds convenience and
management features specific to I2P like protocol handlers and native messaging
systems.

Features

• [done] Provide a way to launch into an I2P-Specific contextual identity
  (container). Intercept requests to .i2p domains and automatically route them
  to the I2P container. Isolate the router console from other local
  applications by automatically intercepting requests to the router console to
  another container.
• [done] Indicate the I2P browser is in use visually. Find an
  acceptable way to indicate it on Android.
• [done] Set the http proxy to use the local I2P proxy automatically.
  Provide specific configuration for other types of I2P proxies(SOCKS,
  isolating HTTP)
• [done] Disable risky webRTC features/offer the option to re-enable
  them with the proxy enforced.
• [done] Change the color of the browser window to indicate that I2P is in
  use
• [ready/broken/wip] Provide help in a variety of languages.
• [wip] Monitor the health and readiness of the I2P router it is
  instructed to use. Currently the plugin checks whether the HTTP Proxy is
  working by fetching an image from "http://proxy.i2p" and displaying a result.
  A work-in-progress binding to i2pcontrol is available in ./i2pcontrol, it is
  inert at this time.
• [Done] Handle router console applications under their own origins and
  within their own contextual identity. (1) The router console is automatically
  confined to it's own container tab. (2) Use a custom protocol handler to
  place each i2p application/plugin under it's own origin, shortening router
  console URL's and placing applications under their own origin.
• [wip] Handle Torrents by talking to i2psnark-rpc plugin and then
  adding them directly into the Firefox downloads drop-downs, menus, etc. If I
  can. Right now instead of talking to snark-rpc, it uses a web-based protocl
  handler that simply auto-fills the torrent into i2psnark.
• [barely started] Isolate traffic by contextual identity to it's own HTTP
  Proxy tunnel, each reflecting it's own pseudonymous identity within I2P. The
  contextual identities. For now, the contextual identities used to manage
  browsing are "I2P Browsing" and "Web Browsing" where I2P Browsing is capable
  of using an outproxy but in the case of traffic destined for the clearnet
  does not do header rewriting, and Web Browsing falls back to the Proxy
  configured in Firefox. The I2P Browsing will be expanded to
  • I2P Amnesiac Browsing: Use for General Browsing, stores no history and
    uses an HTTP Proxy with a very short tunnel-close timeout and no key-reuse.
  • I2P Social Networking: Use this for logging into social network accounts,
    forums, and other interactive asynchronous public communication platforms
    where your identity is behaviorally linkable. This has a very long
    tunnel-close timeout and key-reuse until specifically invoked.
  • I2P Blogging: Use this for posting content to the web interface of your
    blog or to other similar websites that you create content on.

Super Extra Important Background Info:

This plugin's viability is directly related to the viability of Mozilla and
Tor's work on hardening Firefox itself and of particular interest are the
"Uplift" and "Fusion(Firefox Using Onions)" projects.
