Comment 8 for bug 1967963

Kubuntu 22.04, updated yesterday from 20.04 on Acer E15 laptop.

Same issue: each time I start Firefox, it complains it is not the default browser. I click "Set as Default Browser" but the next time I start Firefox, it complains again, the same way.

I tried marking Firefox as default in the browser settings too - no effect.
