Running KDE I’m having a minor problem, that started just recently, several apps, including Firefox, now seem to always open on my secondary monitor. And sure it’s a quick button click to move it back to the primary, but I’m not sure why it’s suddenly always opening up on the secondary monitor in the first place. Is there a way to force a given app, to open on a specific monitor? ---

Yes, you can use window rules for that. Check your window rules in System Settings-\>Window Management-\>Window Rules You may have a rule which is driving it to the secondary monitor. If not, you can add a rule to force it to a given monitor. ---
