It's not possible to enable the dark mode on PDF's within Firefox. It's a security restriction from Firefox. |

If you use Firefox, you can edit userContent.css like this: @media (prefers-color-scheme: dark){
.pdfViewer{filter: invert(1) hue-rotate(180deg);}
}If you use Chrome or Edge, install the extention "PDF Reader", then edit the extention option like this: html[data-theme*="dark"] .pdfViewer{
filter: invert(1) hue-rotate(180deg);
} |

I have a better solution for firefox(I think): @media (prefers-color-scheme: dark) {
.pdfViewer .page canvas {
filter: invert(0.9) hue-rotate(180deg) !important;
}
}It change PDF only and do not have an effect on other things. |
