I2P in Private Browsing Mode(Firefox-Only)

This is an webextension which introduces a set of new "Private Browsing" modes to Firefox-based browsers(Supporting webextensions, must be current ESR or greater) 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, like an embedded I2P console and Bittorrent integration with clients using the transmission-rpc API and via in-browser protocol handling integrations.

Privacy Policy

This browser extension does not collect any personal information. It requires access to local storage and browsing data permissions in order to delete them when directed to by the user. This browser extension does not transmit any information to any third party, nor will it, ever.

This browser extension cannot influence telemetry carried out by browser vendors to determine performance in their distribution channels, nor can it mitigate any other browser vendor telemetry.

This browser extension is entirely Free, Open-Source software.

Installation(Cross-Platform):

For desktop users this addon is available from addons.mozilla.org, where you will be able to recive automatic updates: I2P in Private Browsing.

Setting the Homepage

The first time you run the extension, Firefox will offer you the option of setting your homepage and new tab page to the homepage contained within the extension. You can decline this or edit it later and it will not affect your anonymity. Enabling this feature allows the extension to set your homepage to a local document with a number of useful I2P links.

Debian Installation:

Should you prefer, it is possible to install this extension system-wide by side-loading it into Debian. You can generate your own deb file by running the command:

    make deb

and then you can install it with:

    sudo apt install ../i2psetproxy.js_*.deb

Bittorrent Download:

The self-hosted plugin is available from bittorrent both within the I2P and Clearnet Bittorrent network(With a web seed to support it in case one goes dead).

• magnetsub
• Get the .torrent file

Usage:

• Basically, it "Just Works." After you install the plugin, browsing to an I2P domain will automatically stop the current tab and re-open the I2P site in an I2P Browser tab.
• Besides that, four bookmarks are added to the "Bookmarks Toolbar," which will take you to visit your Java I2P applications, or the "Simplified I2P Landing Page" embedded in the plugin:
• 
• Also, there's a menu for accessing I2P functionality while you're browsing. It lets you control a few settings in a granular way.
• 
• You can re-enable WebRTC but force it to always use the proxy that is enforced by the tab.
• You can either force the browser to delete all history for I2P sites immediately, or you can close all your I2P Browser tabs at once and delete the history for I2P browsing when you're done.
• That's all there is to it! Your browser is configured to safely use and administer I2P.
• Optionally, you can add I2PSnark-RPC and use Bittorrent-over-I2P via the transmission-rpc interface. To do this, have a look at the torrent guide: Torrent guide

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] Provide help in a variety of languages.
• [done] 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.
• 
• [Done] Handle Torrents by talking to i2psnark-rpc plugin and then adding them directly into the Firefox downloads drop-downs, menus, etc. Enable the use of I2PSnark as a peer-to-peer delivery mechanism for media files.
• 
• 
• [Done] Enhance the I2P browsing experience by allowing site developers distribute some or all of their resources as torrents, allowing the torrents to be treated effectively as a CDN.
• 
• [Done] Indicate the level of authenticity provided by TLS. TLS is optional on I2P for now, but some sites offer it anyway. TLS support is experimental and in the works.
• 
• [Done] Provide alternate, in-I2P destinations for web sites that want to mirror their content within I2P.
• [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.

Links about Project Uplift

• Tor Uplift is a project which brings important features of the Tor Browser to the mainstream of Firefox users by including patches from Tor Browser Bundle into Firefox where it is appropriate.
• First Party Isolation is a feature in Firefox and other browsers which keeps information from leaking across first-party domains.
• Fingerprinting is a technique where a tracker attempts to extract unique information about a user from a side-channel in order to create an identifier that can be used to correlate the user across many sites.
• Fennec is Firefox for Android and this link has some analysis of the privacy consequences of the Android platform.
• Tracking in Firefox is surveyed here.

Project uplift seems to have largely been accomplished?

Links about Project Fusion

• Project Fusion or Firefox using Onions is a joint Mozilla/Tor effort to create an enhanced Private Browsing mode for Firefox which uses Tor.
• Notes from a meeting about Fusion.
• Tor at the Heart: Firefox is a blog about Tor and the relationship they have to Firefox re: TBB, Fusion.

The Other Version

New versions of this extension create an I2P in Private Browsing mode instead, using container tabs.

Since this is a drastic change to the behavior of the old plugin, and since there is no UI a new entry for the new plugin has been made at a new location on addons.mozilla.org.

• This is the new version: [link]

• This is the old version: [link]

Android usage:

Use the old version, on either an old version of Firefox(pre-68) or by enabling this custom collection: [Recommended Plugins] https://addons.mozilla.org/en-US/firefox/collections/14614396/I2P-Browser-Fork/
