High CPU Usage on Settings Tab

[Guest]

NS 10.1.3r3 uses a high amount of cpu on displaying the settings tab. seleting a item and clicking an icon to show the line with the checkboxes brings about 35% CPU Usage on a Standard intel core i5 Laptop in fullscreen. this is reproducable.
making the firefox window smaller, the amount of cpu gets smaller accoring to the size ...

its not *that* issue for now, but it is wasting loads of energy if on battery and needs investigation.

is this a firefox issue or an ns issue?

(I'll just note, that I had caught 100% CPU registering. I'll chock that up to a coinminer [that NoScript allowed]. Or I assume it allowed it. I sure didn't.)
