https pages often are blocked

Posted

Since the latest version 66.0.3 (64-bit) I get messages similar to the following. Often there is no specific error code.


Secure Connection Failed

An error occurred during a connection to secure.tesco.com. SSL peer reports incorrect Message Authentication Code. Error code: SSL_ERROR_BAD_MAC_ALERT

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Ironically the html source shows the page is there and complete. Under 'Preferences->Privacy & Security I have unchecked 'Block dangerous and deceptive content" to no effect.

All is fine under Safari. This is a critical issue as I am having to abandon my much preferred Firefox for Safari, which does not have issues.

MacOS 0.14.4 (18E226)
