ColorZilla is definitely my favorite for color work :) I also run StayFocusd and uBlock Origin, though they have nothing to do with dev specifically.
Also, as a copy editor, I have to strongly disagree with Grammarly. I've given it sample writing out of curiosity in the past, and it's always made egregious errors and "improvements" that made the writing worse.
Thanks for your input, I use it mostly for spelling...
