Firefox for Windows 10 ARM is Ready for Testing

Make no mistake, the days of everyone using an ARM-powered laptop or desktop is still several years, or longer, away. But it’s not hard to see how one day, the idea of using a SnapDragon chip instead of something from Intel or AMD for your laptop will become a wide-spread reality.

The last generation chips from Qualcomm, the 835, never haven’t caught on in a big way but as both Microsoft and Qualcomm continue to push forward, there is no doubt that they are making serious progress in terms of performance at the chip and OS level.

So much so that Microsoft has prototype Surface Pro devices floating around that use Qualcomm chips instead of Intel’s hardware. The company has considered replacing the low-end Pro devices with Snapdragon chips but so far, has yet to ship any products that do so for various reasons.

When it comes to supporting Windows 10 on ARM, developing applications is easier today than it was back in the Surface RT era and if you want a different browser than Edge, you can now download FireFox. Firefox and Qualcomm showed this browser off back in December but now it’s ready for testing.

If you have a Windows 10 device powered by an ARM chip, you can grab the browser from here.

While this may not be an Earth-shattering announcement, the more companies who start natively supporting Windows devices running on ARM hardware, the easier the transition will be from classic setups that use x86, to an ARM-based future.

Couple this news with Windows Lite and a laptop running an 8cx becomes a lot more lucrative of a proposition. Only time will tell if ARM and Windows have a long-tailed future but with each new application, chip, and OS update, the possibility becomes a little bit more appealing.

      <blockquote><em><a href="#419896">In reply to skane2600:</a></em></blockquote><p>Well, like you said, ARM is a hype. It's just another closed platform, and most arguments today sound like it's a change only for the sake of change and not because it's particular better. Certainly, the lower energy consumption (and therefore longer battery life of the device) of these processors is a pro, but I wonder if Qualcomm &amp; Co. can really keep that up once an ARM processor becomes as powerful as a AMD64 one.</p>

      <blockquote><em><a href="#419896">In reply to skane2600:</a></em></blockquote><p>Agreed. If you absolutely need win32, Windows x86 is your only choice (ARM x86 emulation is still very poor), but those requirements are getting less and less. If you just use a web browser, or PWA apps, you do not really need Windows anymore, and a Chromebook for example, will meet all requirements.</p>

It also worth noting that most Chromebooks don't use ARM processors which suggests that don't fulfill any critical role.</p>

      <blockquote><em><a href="#419896">In reply to skane2600:</a></em></blockquote><p>ARM is not a hype, modern ARM CPUs are besting Intel cpus in all market segments. They are putting the fire to Intel's feet even in the server market now, forcing Intel to bring CPUs to market with TDPs of up to 400 W. For notebooks, they are cheaper and tend to have very good battery life. As long as enough apps run on them natively, who cares about Win32 compatibility. I think plenty of people will be happy if Microsoft Office, Google apps, Chrome and one or two other select apps run on it. </p>

And ARM has announced its server cores which are expected to give roughly twice the performance-per-watt (on a per chip basis). Fujitsu has announced that its next supercomputer will be based on ARM cores (rather than the SPARC architecture).

    <p>As someone who needs to use a _computer_ (an engineer, programmer) I would *never* use ARM for such work and don't expect to in my lifetime. There's absolutely no reason, and a million reasons not to even attempt. </p><p>At home, I use/have used ARM chromebook, iPad and of course smartphones. There, ARM clearly finds its place in a way that x86 can't. </p><p>As for Windows (aka win32) on ARM, I guess more CPU competition is good, but seems no point as I only use windows for a couple of programs that are 100% win32/.NET (Visual Studio Shell based) but never, ever run on ARM in any acceptable way, not to mention they probably have custom drivers for external debugging. They feel somewhat heavy on a full blown desktop computer, never mind ARM based. </p><p>For the occasional "grandma" that might be ok with a Windows on ARM laptop for just using notepad or something, in my opinion the ARM Chromebook would be superior. </p>
