I was like this for a long time, but Dark Reader for Firefox and the default OS dark modes are good enough now I'd rather once in a blue moon fiddle with Dark Reader to correct a bad auto-color-assignment than put up with light mode in my browser and terminal overall. Just a thought. Until the last ~2 years, with win11, latest Linux desktops, and recent macOS all facilitating the change (if i couldn't do it everywhere i might still not do it, y'know? But they all actually work pretty reliably now)
