Portable Ungoogled Chromium v107.0.5304

ungoogled-chromium-portable

 

 

Ungoogled Chromium is a free and open-source variant of the Chromium web browser that removes all Google-specific web services. It achieves this with a series of patches applied to the Chromium codebase during the compilation process. The result is functionally similar to regular Chromium.

Without signing in to a Google Account, Chromium does pretty well in terms of security and privacy. However, Chromium still has some dependency on Google web services and binaries. In addition, Google designed Chromium to be easy and intuitive for users, which means they compromise on transparency and control of internal operations.

ungoogled-chromium addresses these issues in the following ways:

  1. Remove all remaining background requests to any web services while building and running the browser
  2. Remove all code specific to Google web services
  3. Remove all uses of pre-made binaries from the source code, and replace them with user-provided alternatives when possible.
  4. Disable features that inhibit control and transparency, and add or modify features that promote them (these changes will almost always require manual activation or enabling).

Key Features

These are the core features introduced by ungoogled-chromium.

  • Disable functionality specific to Google domains (e.g. Google Host Detector, Google URL Tracker, Google Cloud Messaging, Google Hotwording, etc.)
    • This includes disabling Safe Browsing. Consult the FAQ for the rationale.
  • Block internal requests to Google at runtime. This feature is a fail-safe measure for the above, in case Google changes or introduces new components that our patches do not disable. This feature is implemented by replacing many Google web domains in the source code with non-existent alternatives ending in qjz9zk (known as domain substitution; see docs/design.md for details), then modifying Chromium to block its own requests with such domains. In other words, no connections are attempted to the qjz9zk domain.
  • Strip binaries from the source code (known as binary pruning; see docs/design.md for details)

Enhancing Features

These are the non-essential features introduced by ungoogled-chromium.

  • Add many new command-line switches and chrome://flags entries to configure new features (which are disabled by default).
  • Add Suggestions URL text field in the search engine editor (chrome://settings/searchEngines) for customizing search engine suggestions.
  • Add more URL schemes allowed to save page schemes.
  • Add Omnibox search provider “No Search” to allow disabling of searching
  • Add a custom cross-platform build configuration and packaging wrapper for Chromium. It currently supports many Linux distributions, macOS, and Windows.
  • Force all pop-ups into tabs
  • Disable automatic formatting of URLs in Omnibox (e.g. stripping http://, hiding certain parameters)
  • Disable intranet redirect detector (extraneous DNS requests)
    • This breaks captive portal detection, but captive portals still work.
  • (Iridium Browser feature change) Prevent URLs with the trk: scheme from connecting to the Internet
    • Also prevents any URLs with the top-level domain qjz9zk (as used in domain substitution) from attempting a connection.
  • (Windows-specific) Do not set the Zone Identifier on downloaded files
