I've been using the firefox pdf viewer for quite some time and it's worked quite well. Within the last few days though I've developed an issue. When I open a pdf it opens correctly for just a brief second (standard text, white background, nothing unusual) and then switches to something like the attached image (black background/ text and such). I have not changed anything that I'm aware of, though I did just recently install a new firefox update (136.0 64-bit windows 11). I didn't notice any articles or comments about this particular issue here yet, so figured I'd ask for some help. Anyone know how to resolve this? Or other things I should look into? Thanks for your time, Derek
