Part of this PRD.

The Secondary Hero Shelf in the homepage will have a module with some text and a Call to Action on the left-hand side:

We need an admin tool for editing the contents of this module:

• Headline, up to 50 characters, localized
• Description, up to 100 characters, localized
• Call to Action, up to 20 characters, localized, optional
• URL, optional

The localization should work in the same way as the copy for Recommended extensions. The Call to Action and URL go together, so it shouldn't be possible to have one without the other.

The first version of this module will have similar content as currently on the homepage:

• Headline: "Extensions are like apps for your browser."
• Description: "They add features to Firefox to make browsing faster, smarter, or just plain fun."
• Call to Action: "See all extensions"
• URL: https://addons.mozilla.org/extensions/
