Sign in issue with CanadianTire.Ca only on Firefox (works on Brave, Chrome and Edge)

For quite some time now, I am unable to sign in to my account at CanadianTire.Ca I get an error. The signon process goes to CustomerAuth.Triangle.Ca for the email and password input. When I click "Sign In" the return message is a yellow triangle followed by the word "undefined" (see attached).

All other browsers I have (Brave, Chrome and Edge) can sign in without issue.

I noticed that other users have the exact same issue. I have tried all solutions I could find. The browser is up to date as of today (150.0.2 64 bit). I tried troubleshoot mode, clearing the cache, deleting cookies, history .... On the web site I turned off ETP for CanadianTire.Ca and CustomerAuth.Triangle.Com.

I have used Firefox since it was v0.93.

Oops ... the first "CustomerAuth.Triangle.Ca" should be "CustomerAuth.Triangle.Com"
