Help us test the Firefox Nightly on Windows 8

Download Firefox Nightly here. Important: Make sure that Nightly is set as your default browser or else it won't launch in Metro.

Hi there! Thanks for your interest in testing Firefox Nightly on Windows 8. We’ve been working hard to bring the Firefox experience to Windows 8 and have an early version we'd like to share with you. This Firefox is an experimental touch-friendly version optimized for Windows 8 (of course, you can always enjoy the stable, desktop version of Firefox in the traditional, desktop mode).

With that said, you may bump into issues as we continue to improve this early version. With your help, we'll be able to quickly fix the glitches and bring Firefox to yet another platform for you to enjoy.

Helping out is easy, just follow these 3 quick steps:

1. Download Firefox Nightly. This extra guide will help you through the installation process. Make sure that Nightly is set as your default browser or else it won't launch in Metro.

2. Use your new browser regularly! Read the news, send emails, buy stuff online, search for "Grumpy Cat" -- do anything, really.

3. File a bug on bugzilla whenever you encounter one. If filing bugs is not your idea of a good time, that’s okay! Your everyday use will help make this version of Firefox better.

If you have any specific questions about testing on Metro please email metro@mozilla.org. You can also check out the Firefox builds forum or The Burning Edge blog for up to the minute updates to Nightly.

Happy testing!
