Adding extra documentation:

• Optional permission API
• How to request extension permissions at run-time

We did a similar implementation for normal prompt dialogs (Like alert or confirm) that website could requests, see GeckoPromptDelegate for references.

When implementing this API we have to take into consideration Android permission that could be needed to access the APIs, like geolocation must have access to the location permission.
