Firefox Addon: Show Grade of Website

[NoNamePro0]

I think, a Addon for Firefox which shows the grade of the Website is maybe a (good?) idea.

I suggest that it just checks things, which the browser already have, so Headers, SSL Certificate. Or just load the API Respone from https://github.com/mozilla/http-observatory.

The Design could be made like DuckDuckGo Privacy Essentials:

On a click on the grade, there could listed the anti-features and next the pro-features with a click to the full insight to the http-observatory-website (observatory.mozilla.org)

I don't know if i'am here right for this issue, may can a teammember move this issue to the right repository.
