The browsers share the majority of code and features, though there are some minor differences in features and they have different licensing. The Chromium Project takes its name from the element chromium, the metal from which chrome plating is made. Google's intention, as expressed in the developer documentation, was that Chromium would be the name of the open-source project and that the final product name would be Chrome; however other developers have taken the Chromium code and released versions under the Chromium name. These are listed under community packages. One of the major aims of the project is for Chromium to be a tabbed window manager, or shell for the web, as opposed to it being a traditional browser application. The application is designed to have a minimalist user interface. The developers state that it "should feel lightweight (cognitively and physically) and fast". ==Differences from Google Chrome== Chromium is the name given to the open-source project and the browser source code released and maintained by the Chromium Project. It is possible to download the source code and build it manually on many platforms. To create Chrome from Chromium, Google takes this source code and adds: * An auto-update system called GoogleUpdate (some, such as the Debian or Ubuntu community builds of chromium, rely on the package management system of the OS as an alternative) * Integrated Adobe Flash Player (proprietary license and code) * Built-in PDF viewer and print preview * Media codecs to support H.264, AAC and MP3 formats * A restriction that disables extensions not hosted on the Chrome Web Store (for Windows users on all Chrome channels) * The Google and Google Chrome names (both registered trademarks) * An opt-in option for users to send Google their usage statistics and crash reports * RLZ tracking when Chrome is downloaded as part of marketing promotions and distribution partnerships. This transmits information in encoded form to Google, including both when—and from where—Chrome was downloaded. In June 2010, Google confirmed that the RLZ tracking token is not present in versions of Chrome downloaded from the Google website directly, nor in any version of Chromium. The RLZ source code was also made open source at the same time (previously it was proprietary—and although the source is now open the feature was not migrated to Chromium) so that developers can confirm what it is and how it works. By default, Chromium only supports Vorbis, Theora and WebM codecs for the HTML5 audio and video tags. Google Chrome supports these as well as the patent-encumbered AAC and MP3 codecs. On 11 January 2011, the Chrome Product manager, Mike Jazayeri, announced that Chrome would no longer support the H.264 video format for its HTML5 player. In October 2013 Cisco announced that it was open-sourcing its H.264 codecs and will cover all fees required. As of November 2015, Chrome still supports H.264. Linux distributions that distribute Chromium may add support for other codecs to their customized versions of Chromium. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chromium (web browser)」の詳細全文を読む スポンサード リンク
