need help running Plex Media Server (failed to execute... x-www-browser)

When I attempt to run Plex Media Server, I get this error: "failed to execute... x-www-browser"
I don't use PMS very often so I don't know what changes I made to my system that could have caused this. One possibility is a recent manual upgrade to my browser (Firefox v55 to v56).

What happens if you just enter "localhost:32400/manage" in your browser address bar?

That works. It launches PMS in Firefox. Thanks!
I created a bookmark, which resolves the problem. But how do I repair the launcher command?

Double check you've got Firefox set as your web browser in preferred applications. How exactly did you manually upgrade? And why are you using a version of Firefox missing 17 months worth of security patches?

Yes, Mozilla Firefox is listed as my preferred browser under Settings Manager / Preferred Applications.

I followed instructions found elsewhere in this forum to manually upgrade Firefox. I'm sticking with v56 for the time being so I don't have to give up all the add-ons I've come to rely on.
