Firefox 4 is almost here. Check out some awesome Web demos on our brand new demo web site: Web’O Wonder. Screencast here.

Update: 3 more demos: https://hacks.mozilla.org/2011/03/webowonder-round/

Web ‘O Wonder

Firefox 4 is almost here, and comes with a huge list of awesome features for web developers.

In order to illustrate all these new technical features, we put together several Web demos. You’ll see a couple of demos released every week until the final version of Firefox 4. You can see the first 3 demos online now on our brand new demo web site: Web’O Wonder:

Note: Some of these demos use WebGL, and will work only on compatible hardware. Make sure you are using the latest drivers for your graphics card.

Open Demos

These demos haven’t been designed exclusively for Firefox 4. We believe that the Web is not the property of any single browser, which is why we made sure that these demos work on other modern browsers, like Chrome, when possible.

The other big step forward for HTML5 demos is that these are Open Source. Help us improve them! The source code of every single demo is available on Github and we encourage you to fork them and play.

New technologies and new horizons for 400 million users

In these demos, we are experimenting with new technologies, trying to imagine what could be the future of the Web. HTML5, CSS3, WebGL, SVG, blazing fast JavaScript and new APIs. Sounds exciting, but what does it really mean for the user?

It means new possibilities, new ways to interact with web applications. It means richer and more beautiful applications. It means a smoother and faster experience and this is what we want to demonstrate with these demos.

We hope to inspire web developers to use these new technologies. This is just the beginning of a new generation of websites. Web developers now have the tools to change the face of the internet and here you have a few blueprints to start from.

Thank you!

A lot of people were involved in the development of these demos. The Mozilla community is full of talented people that did a lot of incredible work to make these demos happen. I just want to say a big thank you to all these talented people (and make sure to check out the credits on the demos!).

Oh, look! A screencast:
