* Bug 1746439 - crave.ca login broken with dFPI enabled
*
* Crave.ca relies upon a login page that is out-of-origin. That login page
* sets a cookie for https://www.crave.ca, which is then used as an proof of
* authentication on redirect back to the main site. This shim adds a request
* for storage access for https://www.crave.ca when the user tries to log in.
