The Mozilla Foundation has released the code for its next-generation Firefox 1.1 browser, codenamed Deer Park Alpha 1.
The latest version features enhancements including a "sanitise" button that automatically clears out browsing history, cookies, cache, form information, and other personal data.
Faster navigation backwards and forwards between pages has also been built in, as has the ability to view thumbnail images in a separate tab bar.
"Deer Park Alpha 1 is a very early stage version of our next-generation browser, and is intended for the developer and testing community only," said the Mozilla Foundation.
"We are making Deer Park Alpha 1 available to our community for feedback and Q&A purposes at this point, and do not intend it for general usage by our end users."
No time scale has been given for final release of the Deer Park browser. Developers and testers can download the code here.
