They can't. As a workaround you can check the cert for the domain here: https://www.ssllabs.com/ssltest/

I mean directly from the Android phone running Pie itself. the same that I can do on a desktop.

Can it be done?

Hi

I recommend that you try this add-on that will allow you to see website certificate information:

https://addons.mozilla.org/en-GB/android/addon/certainly-something/

I use it myself and it is really good.

OK. I guess Firefox on android is not capable of displaying Certificate detailed (Fingerprint, validity dates,etc) information as it does on a desktop workstation.

thanks for the suggestions.

Hi

The add-on that I mention above will show certificate validity dates and fingerprints.

How can certificate details be viewed in android?

I have the same problem. And in addition, I am not allowed to add plug-ins, and the URL I which want to check, is in internal (large) network. Therefore I can not use SSL check sites in the Internet.

I would like to raise a feature request, to bring this certificate view capability into Firefox Mobile (both Android and iOS)
