Some people are having trouble using FireFox.

I came across this last night and solved it this morning. The problem is in the new “Enhanced tracking protection” in Firefox. Turn it off for the login site only - click on the little blue shield next to the lock icon on the url bar. This is in the #support category so Roon will note this.

As to your original problem, if you would just follow the advice I gave you, your problem would be solved.
