Put the extension on the Microsoft Edge Addons store

[github-account1111]

Before you start.

• I have checked the Rejected Features page.
• I have searched the issue tracker for a feature request that matches the one I want to file, without success.

My great idea for Fraidycat is:
I suggest adding the extension to the Microsoft Edge Addons store to increase discoverability and make installation easier for Edge users.
It can also help prevent the possible attack surface expansion which enabling "Allow extensions from other stores" could entail.
