As part of the latest Windows 10 PC Insider preview build 14316, there's also a new version of the Microsoft Edge web browser that adds support for two new extensions, along with updated versions of previous extensions.

Windows Insider head Gabriel Aul stated:

"A few weeks ago, we announced the availability of extension support for Microsoft Edge with more on the way. Today, we are excited to share with you some new extensions that you can try out – Pin It Button and OneNote Clipper. In addition, we have updated versions of Reddit Enhancement Suite, Mouse Gestures, and Microsoft Translator. To install these new extensions, just click on "More" (…) at the top right in Microsoft Edge and click "Extensions" to open the Extensions pane and click "Get extensions".

However, there is an issue in this build of Microsoft Edge that users of the previous preview version should be aware of, according to Aul:

"Please note: There is change in this build that will break existing extensions installed on your PC in Microsoft Edge if they were previously installed using an older build. You can download the new installation files and re-install the existing extensions using the new installers."
