In the previous version I could run streaming videos from Paramount Plus, in the latest version I cannot run them. I have no problems running them on Microsoft Edge.

I get Error #111

How can I use Firefox?

You can toggle DRM off/on to see if that makes Firefox (re)load DRM components.

You can possibly check the XHR requests in the Browser Console if this doesn't work.
