Problem type: Site is not usable
Description: The game claims unsupported browser version
Steps to Reproduce:
Logging in to facebook, running Angry Birds Friends, it just blanket does not support.
In a Chrome incognito tab it doesn't give me an "unsupported browser" warning, but it also renders blank, so.
