amazing how this extension works right of the bat.
glad this doesn't collect telemetry data as well.

This addon is awesome. I don't know how people can live in the world of white without this addon! Only complaint is that it doesn't seem to work on linkedin.com and in not-to-frequent cases it will change the background to a patterned gray/white dot background.
