I'm using the new Firefox Preview on Android (https://play.google.com/store/apps/details?id=org.mozilla.fenix&hl=en), and was wondering if installing the cert is needed. I forgot about it for a while, and while using Firefox Preview I didn't notice ads. Is the cert really needed for it? Does it even install when tried? Also on the address for it why is it delivered via HTTP, and not HTTPS? Screenshot below from attempting at installing it into the Firefox Preview browser. I don't know if it even worked.
