I normally access myaccount.shaw.ca using the URL
When accessing myaccount.shaw.ca with Firefox Quantum 64-bit I receive the following response:
"The owner of myaccount.shaw.ca has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

With Google Chrome Version 71.0.3578.98 (Official Build) (64-bit) I recieive:
"Your connection is not private

With Chrome, if I do not use the https:// at the beginning of the URL, the website seems to redirect to the normal sign-in form without complaining about an expired xcertificate.
