Dark Reader is great with nearly everything except Google Sheets for some reason, which is why I seek an alternative:

1. Install and enable Dark Reader
2. Open Google Sheets and type some text in cells
3. It's also dark and illegible, but the font color is normal if Dark Reader is turned off for Google Sheets

This is unfortunately important because a massive amount of my work depends on Google Sheets. Other than this one issue, it works well with everything else.
