X3DOM (pronounced X-Freedom) is an experimental open source framework and runtime to support the ongoing discussion in the Web3D and W3C communities how an integration of HTML5 and declarative 3D content could look like.

The official site tell us about the browsers and X3DOM.
Internet Explorer 9 = does/will not support WebGL. So you have to install the InstantReality-plugin or Flash 11.
Google Chrome ver 9.x = supports WebGL natively.
Firefox >= 4.x = supports WebGL natively.
Safari (Mac only: Safari 5.1 on OS X 10.6 and 10.7) = include support for WebGL (Windows version does not), but you need enable it through the “Developer”-menu. To activate the “Developer”-menu go to Preferences->Advanced and check the “Show Developer menu in menu bar” button.
