The new Firefox Add-on SDK for Windows, Mac and Linux enables local development of add-ons, while the Firefox Add-on Builder Beta provides a hosted Web-based build environment. Developers can build Firefox Add-ons for all platforms that install and update without requiring a browser restart or interrupting the Web browsing experience.

Firefox for Windows, Mac and Linux now supports the CSS Animations standard to enable developers to build more amazing Web applications and websites. Firfox 5 had added new features such as improved canvas, JavaScript, memory, and networking performance; improved standards support for HTML5, XHR, MathML, SMIL, and canvas; and improved desktop environment integration for Linux users.

Firefox for Android now includes the Do Not Track privacy feature in this release, making Firefox the first browser to support Do Not Track on multiple platforms. Mozilla created Do Not Track to give users more control over the way their browsing behavior is tracked and used on the Web. The feature, which lets users tell websites that they wish to opt-out of online behavioral tracking, is now easier to find in Firefox Preferences. Users with Firefox for Android installed will receive a notification to update to the latest version.
