About this extension
Wanted to play the new Blue Archive event mini-game, but got stuck on a black screen? That's thanks to our good old friend, CORS Missing Allow Origin.
Fear not, however: WE'RE CCC! We'll set you back on track in no time!

The gist of it is:
- The mini-game's assets are hosted on a separate server
- Your browser asks the server if the mini-game page is allowed to use those assets
- The server remains silent
- The browser refuses to load the assets, in case you're on a malicious page

To fix this, the extension tells the browser that it's safe to load the assets.
It affects as few things as possible to keep things secure.
