I normally access myaccount.shaw.ca using the URL https://myaccount.shaw.ca/
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.
Websites prove their identity via certificates, which are issued by certificate authorities. Most browsers no longer trust certificates issued by GeoTrust, RapidSSL, Symantec, Thawte, and VeriSign. myaccount.shaw.ca uses a certificate from one of these authorities and so the website’s identity cannot be proven."
With Google Chrome Version 71.0.3578.98 (Official Build) (64-bit) I recieive:
"Your connection is not private
Attackers might be trying to steal your information from myaccount.shaw.ca (for example, passwords, messages, or credit cards). Learn more
NET::ERR_CERT_SYMANTEC_LEGACY
"
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.
I've getting the exact same thing in the last week or so.
