Firefox cannot open Wayland display

Running 127.0.1 (64-bit) on EndeavourOS, KDE Plasma, using Wayland. I've had severe crash issues and when troubleshooting I noticed this

Error: Failed to open Wayland display, fallback to X11. WAYLAND_DISPLAY='wayland-0' DISPLAY=':1'

pops up every time I start Firefox via terminal. Why wouldn't Firefox be able to open a Wayland display? Trying to force it with MOZ_ENABLE_WAYLAND=1 firefox doesn't do anything. I get the same error message.
