I use Outlook.live.com Hotmail and recently a PopUp Message appears asking me to: 

Add outlook.live.com as an application for mailto links.

Microsoft Customer Service said it was not something they initiated and likely a Firefox issue.

It does not seem safe to click on a random link like this without any explanation. Each time I log in, the same message appears.

Could someone please explain what this is for and how I can stop it from popping up each time I log into Hotmail?

It only adds the Outlook website as an option for opening mailto links, click "Add Application" and it will stop prompting. You can still choose how to open mailto links in the Applications list in settings. If you don't want to ever handle mailto links, you can change network.protocol-handler.external.mailto to false in about:config.
