Anything that strays from the defaults (especially in windows) risks getting reset during a major automatic update, and now you’re getting support calls because “the internet doesn’t work right anymore”.
I’ve never had a update change my default browser. Feels pretty low risk, especially if you get them used to clicking the specific FF icon and hide all Edge shortcuts. They’ll forget it exists quickly.
This is the golden answer.
