Go to the extension’s page in Edge Add-ons and click Get.

Edge asks you to let the extension manage your downloads. Click Add extension.

About the downloads permissionA Java Web Start application starts when the browser downloads its .jnlp file. The extension watches for those downloads: when one starts, it stops the download and runs the application in a new tab instead. It leaves other downloads alone.
Step 2
Once the extension is installed, its icon appears to the right of the address bar. If it isn’t there, click the puzzle-piece icon to list your extensions, open the extension’s menu (three dots) and select Show in toolbar.

Run your first application. If you use the extension for work, activate your licence.
