You can load and get into game with Firefox, you can click the proceed anyway link at the bottom to try it, however performance is worse and some features don't work. Namely Firefox is missing support for the `FileSystemFileHandle` locking mode which prevents multiple tabs from running (cannot share file handles), and they have a negative standards position on implementing some other parts of the File System Access API like `showDirectoryPicker()`.
