I have chosen not to trust:
Go Daddy Class 2 Certificate Authority
I go to https://www.online-billpay.com/ which uses a cert signed by a cert signed by the above.
I get the (correct) message that ‘Safari can’t verify … ’.
One option is ‘Continue’.
That leads to a seemingly infinite loop of such messages.
Ditto Safari 5.05
Here is probably the same bug acting more bizarrely.
I have chosen not to trust Equifax Secure Certificate Authority
I launch Webkit. I empty the cache.
I enter the following into the address bar:
and click on the 2nd link of the ‘References’ whose URL is:
I get a dialog box saying "Safari can’t verify the identity of the website “developer.mozilla.org”."
The cert is signed by Equifax and so this is expected.
I click "Continue".
At this point I get two new items on the screen, both inappropriate:
First a new dialog box "Type your password to make changes to your Certificate Trust Settings." but I have made no changes and do not plan to.
Second the standard "Keyboard Viewer" which is active and shows characters as I type.
2.4 GHz Intel Core 2 Duo
OS X 10.6.8
This is reproducible.
There are no Console messages unless I cancel the password dialog box which produces:
