Can I get an alternative browser (Firefox/Chrome) on Win8 RT?

Where can I find Firefox or Chrome for Win8 RT? I checked both google.com/chrome and firefox.com, but they seem to only have x86 version of the browser, but not ARM.

Neither is available as MS won't allow third-party apps full access to the system. This blog post from Mozilla outlines their objections to this policy.

It’s reported that Windows RT (the name Microsoft has given to Windows running on the ARM processor) will have two environments, a Windows Classic environment and a Metro environment for apps. However, Windows on ARM prohibits any browser except for Internet Explorer from running in the privileged “Windows Classic” environment. In practice, this means that only Internet Explorer will be able to perform many of the advanced computing functions vital to modern browsers in terms of speed, stability, and security to which users have grown accustomed. Given that IE can run in Windows on ARM, there is no technical reason to conclude other browsers can’t do the same.

From Firefox

Does Firefox work on Windows RT?

Firefox is not available for Windows RT.

From Google

(Chrome won’t run in WinRT, i.e. Windows 8 on ARM processors, as Microsoft is not allowing browsers other than Internet Explorer on the platform.)

There is no real technical reason or Windows Store rules preventing Google or Firefox from bringing their browser to Windows RT. They have full access to the Windows RT API and have no reason to even need to access the desktop on Windows RT.

I also didn't hear Firefox or Google whine when they couldn't write a browser for iOS.

I really wish these browser companies would just stop whining about every choice Microsoft makes already.

IE is the only browser to be provided access to the Desktop on Windows RT, and most probably as long as MS doesn't attain a monopoly in the market with WOA (Windows on ARM), this state of affairs will continue.

At this point it is unclear whether WinRT APIs solely without access to Desktop mode can enable creation of any other browser for WOA. Interestingly I did find UC BrowserHD that can run on ARM and thus WinRT, but I don't know whether it's just a "skin" for the IE Trident engine (couldn't find details on its site). I'll look into it further and perhaps try it myself, but if it's truly an independent browser for WinRT then that's quite an achievement and most likely the first of its kind.
