Firefox 72.0a1 and 71.0b11 on Windows 8.1

In the certificate viewer, the l10n string id 'certificate-viewer-inc-locality' gets used but that string doesn't exist.

Steps to reproduce:

1. Open https://www.deutsche-bank.de/pk.html
2. Click on lock symbol in address bar.
3. Click on the right arrow ">" next to "Connection secure".
4. Click on more information at the bottom of the pop-up.
5. The first line mentioning Frankfurt am Main has no bold label next to it.

The source code shows that a l10n id gets used here:
<label data-l10n-id="certificate-viewer-inc-locality"></label>

A searchfox search returns nothing for certificate-viewer-inc-locality.

I think it would be relatively safe to:

1. Add the missing Fluent ID to certviewer.ftl
2. "Migrate" the translation that we have for certificate-viewer-locality, given that the label and context are the same.

Shayna, would you like to work on this bug? The comments above should provide enough instructions to get started, but please let me know if you need any help.

Thanks!

Yes, I would. Thank you! I'll let you know if I need any help.
