Change app recommendation settings

When I try to download an app to my Windows 10 PC, I get the message, This app is not a microsoft verified app. Change your app recommendation settings. I've tried and failed. I go to settings, app, apps and features and there is no option there. The
only options are Optional features and App execution aliases. My PC is running Windows 10 Home 1909. How can I change this?

 

New Windows Media Player Plugin for Firefox

Anyone who uses Windows Vista and Mozilla Firefox may be pleased to hear that the Windows Media Player team has now released a plugin for Firefox that should allow the browser to play WMP content on websites. Here are the steps to get it working:

• Installation of the Windows Media Player Firefox Plugin may require administrative access to your PC. It is recommended that you close all other open browser windows before continuing with the installation.
• Click the Install button to automatically download and install the Windows Media Player Firefox Plugin.
• Depending on your security settings, you may see a Security Warning dialog box. Click Install to install the plugin.

There is a known issue if you are using Firefox version 2.0.0.3 on Windows Vista with the installer failing with error code -203. To work around this simply restart Firefox (you will get a notification that Windows Vista will be changing the Firefox compatibility settings) and then install again - the second time should succeed.

The download is available here, and the new plugin works on all versions of Windows XP and Windows Vista (although it is mostly intended for Vista, as that currently has no WMP support in Firefox).

Set Firefox as default .pdf reader

I used to use Firefox as my default .pdf reader. Somehow, the default app was changed to Evernote. When I went to Default App Settings for .pdf files, Edge (of course), Chrome, and Opera were listed as options but not Firefox. How do I add Firefox as an option for my default app?
