More security information on Android

[Cyc]

Firefox for Android shows only "Connection is secure" and the name of the Certificate Authority when you tap the lock in the address bar. I would appreciate a more details of the certificate (valid from/until, key type, fingerprint, alternative names) and also the TLS version and cipher. This is very useful to have in a mobile app when you quickly have to verify whether a certificate was renewed or have to debug trouble with HTTPS.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

Chromium has way more infos than this, especially infos on insecure connections.

I cant find the test website, but there is one with various insecure TLS traffic sites and the Chromium warnings are a lot more verbose.

This would also help with inspecting self-signed certificates for home appliances (like routers).

This is what Chromium shows:

1. Certificate error page2. Activating the little lock icon in the address bar opens up a dialog showing the TLS version and cipher in use.3. Activating the link named "Certificate information" opens up another modal dialog with a lot of certificate info, such as fingerprints, expiration dates, CN, etc.

This is what Firefox shows:

1. Certificate error2. Activating the little lock button on the address bar will lead you to this very tiny dialog box that says nothing useful about the certificate.

It should be displaying the fingerprints, at least. It should also warn you anytime the certificate changes (requiring confirmation), and remember your choice to permanently add an exception for it (this was requested here).
