rpm -e gave error messages, but yum remove did the trick.
And THEN:
The login screen popped up, and everything worked as it used to work
after logging in.
I am very grateful for all good help, I have learned a lot from this, I
have some more understanding of how Java plugins work, but also how
Firefox deals with plugins.
I will study Java more and use it for some purposes,
then I don't have to ask so many uninformed questions - hopefully.
