The proposal here would be to further develop the protections dashboard allowing:
1 - Showing statistics of other privacy add-ons. For example, allowing an extension like uBlock Origin to populate the number of trackers blocked, cookies, etc. That would really show how hardened and safe Firefox is, even with third-party add-ons.
2 - Show tips and tricks about security and how to stay safe online. This could go from simple paragraphs to links to Youtube videos from Firefox.
