Mozilla Prepares Firefox 4 RC for Launch

MOUNTAIN VIEW, Calif. — Mozilla has unveiled a new HTML5/CSS 3 showcase to demo some of the new web standards coming in Firefox 4.

Mozilla’s new Web o’ Wonders website website will work in any modern browser, though the video elements use the WebM codec, so Firefox 4, Chrome or Opera is needed to watch movies. Mozilla’s Web o’ Wonders doesn’t conflate the various new web standards under the singular banner of HTML5 — SVG, JavaScript, CSS 3 and HTML5 are all called out separately, by name.

Currently, there are only three demos on Web o’ Wonder, but Mozilla plans to add more, and developers can submit experiments for consideration. The three experiments of the site now showcase HTML5 video, WebGL rendering and various CSS 3 and JavaScript techniques combined under the heading “design.”

The HTML5 poster experiment covers just about all the new HTML5, CSS 3 and JavaScript support in Firefox 4. Developers can click the “learn more” link to reach Mozilla’s developer page for each new feature listed.

Google and Microsoft both released similar efforts to showcase Chorme and IE9. And, there was Apple’s effort, but because of some poor coding decisions, Apple’s showcase only works in Safari.

Firefox 4 RC is expected to roll out in early March.
