These are the goals of the I2P Browser, and not really this plugin in-and-of-itself

A

User Interface:

  • Remove search engines
  • Replace bookmarks
  • Donate banner / UI
  • Patch Firefox to have relative (from the binary) profile directory
  • Start use the Firefox update process to update browser installations
  • Mark .i2p cookies as secure
  • Mark .i2p domains as secure connection
  • Add tests for .i2p secure marking
  • Improve the delay-the-user XUL dialogs to be more accurate in regards of where the router is in it’s bootup progress
  • Disable the WebIDE
  • Disable GamePad API by default
  • Disable Web Speech API by default
  • Disable the Web Audio API by default
  • UI redesign bootstrapping and configuration screens (delay-the-user dialogs)
  • Default browser choose wining should de disabled like browser.shell.checkDefaultBrowser, it can be default, but then choosen by the user without any begging ahead
  • Extend the firefox preferences UI for I2P router configuration thought of as "must have" or "very nice to have"
  • Shrink the BroadcastChannel API's boundaries of access or disable completely
  • Make a API white/grey/black -list, in super paranoia mode we should probably disable almost all, while in most cases the user probably want to be as close to a normal browser/web experinence that they are used to from before

Leak Avoidance:

  • Stop web socket DNS leak
  • If doable, slim down the CA store from unnecessary CAs
  • Disable the microphone by default
  • Ensure WebRTC is disabled in compile time
  • Disable mDNS features
  • Ensure links like sftp:// and smb:// , as well as \samba-share is blocked/denied
  • Don’t allow IndexedDB storage for third party domains (likability issue)
  • Patch the DNS service to prevent any browser or addon DNS resolution
  • Restrict what MIME types that are exposed to content scripts

General Security:

  • Backport any security patches that might appear from Mozilla
  • Don’t allow XHR/Websockets requests towards 127.0.0.1/localhost
  • Always use the most sane form of preferences defaults in context of privacy and security.

Unnecessary Connections:

  • Disable getpocket.com features and alike
  • Remove sync option from preferences
  • Clear state when the app exits, by default
  • Disable updater telemetry
  • Make firefox stop call home to mozilla for different reasons
  • Prevent non-Necko network connections
  • Figure out how to approach prerender, preconnect, and prefetch link tags

Disk Avoidance:

  • Don’t allow SSL key logging
  • Only cache media in memory
  • Disable the password saving functionality to avoid such being written to disk
  • Disable the Auto form-fill to keep as much as possible not written to disk

Platforms:

  • Support for Android?
  • Support for iOS?

Anti-Fingerprinting:

  • Test for preferences which ensures a sane default and something to tell when/if we break it
  • Disable support for system adding
  • Disable Firefox enterprise policies
  • Disable NTLM authentication
  • Disable SPNEGO authentication
  • Handle privacy issues regarding window.name
  • Test runner for I2P Browser test cases
  • Block loading of plugins
  • Disable OS spesific firefox features that can help fingerprint the end user's operating system
  • Block html5 canvas by default
  • Block by default or disable WebGL completely?
  • Never start fullscreen, always start with fixed width/height to avoid expose screen resolution
  • Report fake system uptime to content scripts
  • Spoof Accept-Language and Accept-Charset headers no matter browser language
  • Spoof timezone to always be UTC
  • Develop methods to reduce the accuracy of JavaScript performance fingerprinting
  • Always report only one CPU core (dom.maxHardwareConcurrencys)
  • Avoid Keystroke fingerprinting by messing with the event resolution
  • Disable GeoIP-based search results
