Rated 4 out of 5 stars

May I suggest adding some options, like different settings for individual sites. Just the option to not run on individual sites would be enough. I like the automatic mode but on some sites it whitens light gray text when the background is white and blackens text when the background is black.

This review is for a previous version of the add-on (1.4.7.1-signed). 

EXACTLY what I was looking for. Rated 5 out of 5 stars

I was using Color Transform but that requires clicking the button for every page. This has the Automatic option and does exactly what I wanted without the extra stuff.

Thank you for this addon.
