Please be using an Android device when following the directions on this page.
Installing the SSL certificate for Android devices is a two-part process.
First, use the standard Browser app or the Chrome browser and click the green SSL shield icon above.
You will see a dialog box like so:
Type the name of your choice here, if the field is blank, and click OK.
Firefox does not use the Android System root SSL store, so we must install the certificate directly in Firefox. Launch the Firefox browser and navigate to this page again.
With this page loaded in Firefox, click green SSL shield icon above.
Select "Trust to identify websites." as shown in the screenshot below, and click OK.
