Firefox 58 (Nightly)
Not for the faint of heart – we recommend running Firefox Nightly in a test bed environment only.

Do you ever wonder how programs make it through the testing process? Mozilla’s decision to speed up development of the Firefox browser gives users an unique opportunity to get a close look at this process. But despite the much-vaunted emergence of developmental builds like Firefox Beta and Firefox Aurora for wider public consumption, there’s still a lot of testing to be done even before a version of Firefox reaches alpha, or Aurora, status. 

This testing is done using nightly builds – developers make changes to the code during the “day”, and then at “night” a fresh build is uploaded to the Mozilla servers for developers and hardcore enthusiasts to test. It’s important to know at this point that many of the code changes have not been tested – they’ve been incorporated into the main build, but that’s it. It's now up to the hardy souls who run Firefox Nightly to try out the changes and report back on any stability issues they encounter.

The Nightly build will install alongside other Firefox builds, specifically the Aurora build and the Beta/Stable build. However, it will share access to existing Firefox settings, meaning there is a risk you could lose these if something catastrophic was to happen.

With this in mind, we’d strongly recommend you only install Firefox Nightly on a test machine, or in a virtual environment such as that provided by VirtualBox. Once done, you can safely road test it, secure in the knowledge you’re not going to screw up your main computer by doing so.

Nightly introduces Firefox 58.0a1. You can see what's planned for this version by visiting the Fixtures/Release Tracking page, although note that most of these features are not implemented in Nightly. One interesting point to note is that Nightly also offers a 64-bit version of Nightly for Windows as well as Linux.

Verdict:

Most people should leave Firefox Nightly well alone, but if you’re experienced enough and dead keen to contribute to Firefox’s development, it’s worth checking out – with care.

Windows 10 Fall Creators Update build 1709

Free Full Commercial Software

This is the latest version of Windows - Fall Creators Update. it's a media creation tool that can be used to upgrade an existing installation of Windows or create installation media for another PC. Just make your choice after launching the tool and it'll do the rest.

What was new in Windows 10? The latest release brings back the Start Menu, though with a Windows 8 twist: live tiles keep you up-to-date with the latest news while also providing an easy way to launch apps. (Don't worry if you prefer the Start Screen, it's still there and you can boot into it if you prefer.)

Apps now work much more like regular desktop programs. They have minimise, maximise, restore and close buttons, and can be resized (to a degree) and organised however you like.

If you've still lost track of a program in the mass of open windows, a new Task Spaces feature can help. Click its taskbar button and you'll see thumbnails for everything running now, a little like OS X's Mission Control - just click something to switch to it.

Better still, Task Spaces also supports virtual desktops. Add extra desktops as required and it'll display thumbnails of each one, making it easy to identify whatever you're after and switch to it.

There's also smarter snapping, new customisation options, and even a bunch of experimental additions to the command prompt.

Fall Creators Update brings a whole host of new features for Windows 10. See the Microsoft Blog for more information.

The Windows 10 ISO here will give you build 1607 which is the August 2016 Anniversary Update.
