    The Browser class holds all the data and handles all the
    functionality related to a single browser instance
    This includes (but probably isn't limited to):
    - Fetching resources from URIs
    - Getting/Setting/handling cookies
    - Managing History (allowing forward/back functionality)
    - Managing multiple "contexts", each which has its own histories, but
    shares things like cookies. Think tabs or windows within the same
    browser instance
