After it's been running a while, it starts periodically locking up the browser scrolling and workflow every few seconds. It's like every 10 seconds or so, another hold up, and each hold last a few seconds.

Besides interrupting your workflow, which is irritating, I wonder what else it's actually doing during those momentary holds. Maybe reading your screen, data collection or spying?

I've used this a long time, and while I do like the concept of an unscheduled dark mode switch that you can turn ON and OFF at anytime you wish without any schedules, I find the above problem unacceptable. My browser works normally when I disable this extension.
