Blacker Text szerző: Omega Centauri Software

It has become fashionable to make text dark gray instead of black. That's hard on middle-aged and older viewers. This extension lets you snap dark text to 100% black. You can adjust how dark the text needs to be for the snapping to happen.

Dark gray backgrounds also snap to full black, and a nearly white text or background snaps to white, unless you turn off these features.
