JavaScript Is Disabled
The notation “JavaScript Is Disabled” displays at the top right of your screen if your browser is set to disallow JavaScript. When JavaScript is enabled, your browser uses ActiveX (if Internet Explorer) or a Firefox extension to do the decryption locally. When JavaScript is disalbed, Zero Download still works, but for technical reasons must post your message to a Private Post server for decryption and then send it back to you in a secure transport mode (https://).
Private Post securely deletes the message copy on the server once you have viewed the message.
Apart from the above change in back-end processing, there are a few, minor differences in the user interface of various screens when JavaScript is disabled.
ToolTip icons (
) do not display text when you place your mouse pointer over them. Instead, you must click them in order for the message to display, and it displays in a small “pop-up” browser window.
Without JavaScript, the password-strength meter on the Register Encryption Account screen does not appear.
When JavaScript is disabled, the Zero Download “enter your email address for authentication” sign-in screen displays three fields instead of two:
Select your email address (drop-down list)
Type your email address if it’s not listed
You sent this secure email
When JavaScript is enabled, you can either select from the “Select your email address” drop-down list or type directly into the field.
