A good time to try Firefox for Metro

“Firefox for Metro” is our project to build a new Firefox user interface designed for touch-screen devices running Windows 8. (“Metro” was Microsoft’s code name for the new, touch-friendly user interface mode in Windows 8.) I’m part of the small team working on this project.

For the past year we’ve been fairly quiet, partly because the browser has been under heavy construction and not really suitable for regular use. It started as a fork of the old Fennec (mobile Firefox) UI, plus a new port of Gecko’s widget layer to Microsoft’s WinRT API. We spent part of that time ripping out and rebuilding old Fennec features to make them work on Windows 8, and finding and fixing bugs in the new widget code. More recently we’ve been focused on reworking the touch input layer. With a ton of help from the graphics team, we replaced Fennec’s old multi-process JavaScript touch support with a new off-main-thread compositing backend for the Windows Direct3D API, and added WinRT support to the async pan/zoom module that implements touch scrolling and zooming on Firefox OS.

All this work is still underway, but in the past week we finally reached a tipping point where I’m able to use Firefox for Metro for most of my everyday browsing. There are still bugs, and we are still actively working on performance and completing the UI work, but I’m now finding very few cases where I need to switch to another browser because of a problem with Firefox for Metro. If you are using Window 8 (especially on a touch-screen PC) and are the type of brave person who uses Firefox nightly builds, this would be a great time to try Metro-style Firefox and let us know what you think!

Looking to the future, here are some of our remaining development priorities for the first release of Firefox for Metro:

  • Improve the installation and first-run experience, to help users figure out how to use the new UI and switch between “Metro” and desktop modes. (Our UX designer has user testing planned to help identify issues here and throughout the product.)

  • Fix any performance and rendering issues with scrolling and zooming, and add support for double-tap to zoom in on a specific page element.

  • Make the Metro and desktop interfaces share a profile, so they can seamlessly use the same bookmarks and other data without connecting to a Firefox Sync account.

And here are some things that I hope we can spend more time on once that work has shipped:

  • Improve the experience on pages with plugins, which currently require the user to switch to the desktop Firefox interface (bug 936907).

  • Implement a “Reader Mode,” like Firefox for Android. (A pair of students have started working on this project, and their work should also be useful for adding Reader Mode to Firefox for desktop.)

  • Add more features, and more ways to customize and tweak the Metro UI.

If you want to contribute to any of this work, please check out our developer documentation and come chat with us in #windev on irc.mozilla.org or on our project mailing list!
