Does anybody know how I can style the Firefox built-in Web Developer (devtools) theme? I am using the Dark theme, and need to make a small change in the way line numbers/column numbers are shown in the console output.
The default color, which is a shade of orange, to my eyes is totally unreadable. I searched the web but all I get is stuff about theming of code that is displayed and analyzed by Web Developer.
Btw., I have to use the dark theme because the lighter themes are even more of a strain on my eyes.
I think this might be what you're looking for. It's the main CSS file for the dev tools. The dark theme is defined here and the used orange is defined here.
I'm not sure if that color can be changing without rebuilding Firefox or creating a browser extension for that.
