Firefox 5 is now available to download just three months after the launch of Firefox 4, bringing with it improvements such as the addition of a do-not-track feature for the Android version of the browser.

The release is the first on the accelerated release cycle, meaning Mozilla plans to deliver a new full version of the browser every three months. The company says this allows it to deliver performance, security and stability tweaks more quickly. Google also delivers full version updates to its Chrome browser every six weeks, but does so automatically rather than requiring a manual upgrade.

"The new version of Firefox comes on the heels of the wildly successful release of Firefox 4, which had more than 200 million downloads on Windows, Mac and Linux," Mozilla said in a blog post on Tuesday. "This release adds support for more modern web technologies that make it easier for developers to build amazing Firefox add-ons, web applications and websites."
In contrast to other browsers with similar privacy features, Mozilla's Do Not Track relies on the header information being relayed to advertising companies, who can choose whether or not to honour the request not to collect data. This feature has also now been added to the Android version of Firefox.
Also on Tuesday, Mozilla launched an add-on software development kit (SDK) and a beta of the Builder hosted online environment, which the company said makes it quick and easy to build add-ons for the browser.
The SDK is aimed at people who want to work on a local machine using a command-line interface and their own development environment, while Add-on Builder is a hosted, online environment that includes tools such as a code editor, module selection and testing features.
