Mozilla had started testing for the Firefox Metro browser designed specially for Windows 8, with Metro interface of the new Windows 8.
It includes many of the usual tools of the new Firefox. “Firefox Metro” has a new interface and also runs on the old too. For those of you who installed the RTM release of Windows 8, you can now download a nightly build of Mozilla Firefox from the Elm development branch and start testing. Elm is the experimental repository where most of our Metro development work has been happening. This repository produces nightly builds, much like the Firefox Nightly channel. Once installed, these builds will self-update so that you can track Metro Firefox development.
This Firefox Metro style Firefox Start page, support for Firefox Sync, Metro touch and swipe gestures, integration with Windows 8 “charms”, and a simple but powerful Australis interface that is streamlined, modern, and beautiful. The rest are minor things like support for Java Script, PDF and HTML 5. However I will closely follow the changes and upcoming updates and will notify you in my upcoming posts.
