We might need to make some adjustments considering the new policy for CSP directives. Needs to happen before Jan 25 2022.

Maybe some of these are the ones required.

• osm for tiles: https://openstreetmap.org/
• firebase for rtirl: https://cdn.firebase.com;https://*.firebaseio.com

Also https://github.com/BarryCarlyon/twitchextensioncsp could be useful

From testing, the ones that are required are: For images:

• 'https://*.tile.openstreetmap.org' For connections:
• 'wss://*.firebaseio.com'
• 'wss://rtirl-a1d7f-default-rtdb.firebaseio.com'
