Screen resolution spontaneously changes

IMac 27" 5k Retina Ventura 13.7.8

Recently, prob since 13.7.7 when I am working on the internet, Firefox 142.0.1 (64-bit), my screen resolution changes spontaneously. I've been to system settings...display and I am on default. Changing the res there makes little difference, if any, and certainly doesn't fix the problem.

The only cure is to reboot.

Any advice appreciated. Thanks
