Run firefox in terminal. It outputs:

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

Note that this error won't happen if firefox is invoked from GNOME Terminal.

This type of issue is typically related to environment differences between VS Code's terminal and the external terminal. You can try diffing the two environments by printing them (eg. env, Get-ChildItem env:) and investigating any differences.

Closing this off as it doesn't look actionable on our end, you can read more about our issue process here. Thanks for understanding.
