A new Firefox Beta for Windows, Mac, Linux and Android is now available for download and testing. This beta adds new built-in developer tools that make it easier and faster to create and modify amazing websites and Web apps. This beta also adds enhancements that make Firefox Sync easier to setup and pair across desktop and mobile devices.

What’s New in Firefox Beta for Web Developers:

• Full Screen API: Developers can create Web applications that leverage the entire screen. The Full Screen API works with any HTML content, enabling developers to build entertaining and compelling Web video and game experiences. You can get more information in this blog post.
• Page Inspector: Page Inspector makes it fast and easy for developers to test the design, style, font, color and page positioning of their website. Developers can see the HTML and CSS rules applied to any selected page element. This makes it easy to navigate through different page elements while viewing the HTML document structure for the page.
• Style Inspector: Developers can use the Style Inspector to see the CSS properties applied to any selected page element and easily change the values to experiment with new looks. You can get more information in this blog post.
• CSS3 3D-Transforms: Developers can create two-dimensional elements that animate and transform into 3D using HTML5 without the need for third-party plugins. You can get more details in this blog post.
• Anti-aliasing for WebGL: Now 3D WebGL content will have edges that blend smoothly, especially with games and animations.
• Scratchpad with Orion Code Editor: The developer Scratchpad adds the Orion code editor, allowing developers to edit more than plain text. The Orion code editor provides syntax highlighting and other great features and makes it easier to write JavaScript.

What’s New in Firefox Beta for Users:

• Add-ons Compatible by Default: Firefox updates are smoother and easier because incompatible add-ons are automatically disabled and all other add-ons will default to compatible (except binary add-ons). We need your help testing the update process to make sure that incompatible add-ons are properly disabled. You can read more details in this blog post or file a bug.
• Enhanced Firefox Sync: Firefox Sync is enhanced with an easier setup process so you can pair your Android phone, tablet or any Firefox-enabled device without needing to be at your desktop computer.

Editor’s note: Amy Tsay recently posted about Default Compatibility for Add-ons. The full post is included below:

The latest phase of our add-on compatibility plan has arrived in Aurora, and we need your help to test it! Since Firefox 4, we have been automatically making add-ons hosted on AMO compatible with new Firefox releases. Now, we have extended automatic compatibility to non-hosted add-ons, which account for 75% of all add-ons in use (currently in the hundreds of millions). This means you should see less of the incompatible add-ons dialog, and more of your add-ons should just work.

You can read more about the plan, including how we determine eligibility for automatic compatibility here. For additional background reading, check out this blog post.

Once you have Aurora installed, all add-ons that are compatible with Firefox 4 or later can be installed without extra steps. Firefox will install them even if they are declared incompatible in the manifest file.

If you don’t already have Aurora installed, you can get it here. With Aurora, you’ll see our newest features before they go beta, and have a chance to send us feedback before the final release.
