Inconsistency: Mandatory manifest keys

[carlosjeurissen]

Background

What manifest keys are required differs per browser.

As baseline, most browsers require manifest_version, name and version.

However, Safari also requires icons and description.

And Firefox under specific circumstances requires browser_specific_settings.gecko.id. See When do you need an add-on ID?.

Potential goals

• Make clear documentation what keys are required for what browsers
• Streamline the requirements across browsers. For example, requiring icons and description for all browsers, or drop the requirement for Safari, as the description can easily be empty and the icon could be some blank default
• Create a single add-on ID which can be used for all browsers / stores
