Haha well this is odd. Definitely wasn’t on the high contrast theme.
And after switching to the Card Shadow theme, the entire thing just stayed the same with the very dark background and white boxes.
Using cropped images to reduce the size of my post but basically it looks the same as the first screenshot in my previous post, regardless of the theme chosen and saved. Including the home page outside of settings.
I definitely don’t have any accessibility settings enabled and haven’t encountered this on other websites (yet), although my usage of Firefox is pretty low these days because it’s fairly heavy duty for my phone. I’ll play around with my settings and try a few things though.
Update: not entirely sure what else to try but one thing I’ve tried now is disabling the global dark theme in my settings as well as Firefox (aargh my eyes). This seems to make no difference either. I even switched to the “Trans Pride” theme and it remains the same. The only settings that I’ve modified in accessibility is to make text size smaller.
If you have any suggestions of what to try, I’d be happy to. Otherwise I’ve been needing an excuse to start over on this device. So a reflash might be in order.
