Hi everyone: I started recently to use Librewolf. I know that its better to avoid installing extensions and using dark themes in order to not be exposed to fingerprinting. But what about using the command xcalib -i -a on linux to invert the screen colors and thus achieving the dark theme. Would this information also be leaked to the websites? and how I can check this eventually?

No. That would not leak. You probably also want to rotate hues 180 degrees so that only brightness but not colors are affected.

It happen on your wm, librewolf does not know about it.
