Google is launching the first beta of its Webkit-based browser, Google Chrome, tomorrow! September 2nd.
Here is the Google Chrome Browser Comic book that it is used to explain the technical details of its new browser.
Chrome makes uses of multiple processes, where each tab runs on a separate process. Unlike Firefox, if one tab freezes, Chrome can simply close that tab, not affecting the running of other tabs or the browser as a whole.
Google has a Web site for Chrome here.
