Firebase info bar doesn't have a close option

[karthikch53]

Would be nice if we can have a close icon on the info block which displays info about Firebase. Or, it would be even better if the info block closes when the user hits 'ESC'.

The screen does have a 'Cancel' button at the end of the page. But I agree that it is not evident from the UI. I'll add a Close button at the top.
