Just added the extension to give it a whirl. My CPU usage is 3% to 4%, memory is ~37%, on an i7 wih 16 GB RAM (and about 100 tabs open in Firefox).

I like it. I was looking for something like that for a while. Nighttime browsing on LED monitors seriously hurts my eyes, even with night light settings on. This looks like it'll do the job. I'll know tonight :)

Wish you luck. The resource usage spikes I was experiencing were happening sporadically and some sites were more prone to it than others. I've just installed it again, we'll see how it goes.
