Capability of S/MIME support for OWA on Firefox

Hello Firefox! I wanted to understand if there is a way for a user to login to Outlook WEB ACCESS. If you login to OWA on Firefox, is there a capability to have S/MIME active?

I have researched that this is possible on EDGE, and did some research on Google to see if this is common.

Would there be a FAQ or guide on this topic?

Hi Ian, it looks like you need an add-on from Microsoft to use S/MIME in your browser. If they have an add-on for Firefox, it appears to be a well-guarded secret.

Well, maybe it doesn't exist. The following article says:

S/MIME in Outlook on the web in Exchange 2019 is supported in Internet Explorer, Edge, Edge with Chromium, and Google Chrome.
