I signed it!

We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for the commit author(s). If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google.

CLAs look good, thanks!

Great ! Thank you for the PR ;)

I'd like to question what uses "global"

Edit: or perhaps question the order of operations. Perhaps prioritize window would work nicer? I currently ran into an issue where I had no idea that "global" was used in any way until I discovered the closure setup. I had to go around and refactor everything just so I could use firebase.
