The new Windows 10 Mobile build 10512 that's now available for download for Windows Insiders enrolled in the fast ring does come with some improvements here and there, but as far as the brand new Edge browser is concerned, it's the same feature lineup as in the previous build.

But that's going to change soon, as the Windows development team is planning to introduce major improvements to Edge in the coming builds, as revealed by a Microsoft engineer.

Microsoft Edge is Redmond's big bet for the browser war, replacing Internet Explorer after nearly 20 years of being offered as the default option in Windows. But Edge indeed comes with a wide array of new features and a fresh UI, as well as a new engine that's supposed to be a lot faster and more reliable as compared to its predecessor.

On mobile devices, Microsoft Edge is supposed to come with the same feature lineup as on the PC, as the browser will be offered as a universal app and should offer a similar experience across all devices.

That's why Microsoft is now planning to make some big changes to the mobile browser, trying to bring it in line with the PC version that's already available for everyone in the RTM build.

Extensions coming on mobile too

What's interesting is that Microsoft is aiming at offering the exact same features on all devices, so when extension support arrives on PCs, the company will start working on bringing this functionality on mobile devices too.

Extension support in Microsoft Edge will allow the browser to run Google Chrome extensions, either with no modification or only small changes to the original code.

This feature is projected to be released sometime this year, most likely in October, as part of a major update that will include several other improvements to the core Windows 10 operating system.
