Microsoft has officially announced the availability of Windows 10 Insider Preview Build 14342.
Here’s what’s new in Build 14342
Updates for Extensions in Microsoft Edge: Instead of extracting and loading extensions from a local folder, all available extensions can now be downloaded directly from the Windows Store. This change means that your currently installed extensions will be removed, and you’ll have to reinstall the ones you want from the Store. Then in future updates, your extensions will be automatically re-downloaded and installed.
We also have some new extensions available for you to try out. We are excited to announce that starting with this build, both AdBlock and Adblock Plus are now available for download in the Windows Store in addition to Pin It Button, Mouse Gestures, Reddit Enhancement Suite, Microsoft Translator, and OneNote Web Clipper. It is recommended that you only install one of either AdBlock or Adblock Plus as having them both running at the same time can cause issues with viewing websites in Microsoft Edge.
Important note: There is a bug in this build that occurs if you turn off all extensions without uninstalling them, you may not be able to close the browser or get context menus to work. To avoid this issue, uninstall any extensions you no longer want to use instead of turning them off. If you do hit this issue, to get out of this state you will need to turn on one or more extensions or uninstall all extensions, kill any Microsoft Edge processes running in Task Manager, and restart Microsoft Edge.
Real-time web notifications in Microsoft Edge: Microsoft Edge now supports real-time web notifications, which allow participating websites to send notifications to you via Action Center, with your permission. For example, when your friend sends you a message on Skype for Web while you’re busy in the Xbox app, you won’t miss a thing. A notification from the website will appear in Windows, just like an app might send. Click on the notification and you’ll be right back in Microsoft Edge at the site that sent it!
Swipe navigation in Microsoft Edge: Since the release of Windows 10 Mobile, our top feedback request for Microsoft Edge has been asking for the return of the swipe gesture to navigate back and forward. It’s also been one of our top 10 requests on PC. With this build, you can now swipe from anywhere on the page to get back to your previous page. This will be coming in the next Mobile build as well!
