Firefox automatically downloading and opening ISO files

[Thane K. Sherrington]

For some reason, my Firefox 93 has started downloading an opening ISOs in explorer without prompting me.  How can I tell it to save instead (or ask me)?

Thanks,

Is there an entry for ISOs when you go to about:preferences in the Applications section?

That's the odd thing - ISO isn't in my apps under about:preferences.
