I looked at the other comment, it was the Firefox addon dark reader. Turning that off solved my problem in stock Firefox dark and light modes

Sure. I’m using Firefox on Android. I’m not sure if I’m uploading images correctly or not but I’m trying to attach a screenshot of what it looks like for me

I tried switching to light mode and it was still completely unreadable. Grey text on a darker grey background is a very poor choice

Idk if it’s mobile or dark mode, but the page is totally unreadable
