While I appreciate the annoyance is the point; if like me you just can't take it, paste this in your console (only if you understand what it does), then use left and up arrows to rotate and fire:
const fire = document.getElementsByClassName('c-fire-button')[0];
const rotate = document.getElementsByClassName('c-rotate-button')[0];
document.addEventListener("keydown", e => {
if (e.code === 'ArrowLeft' || e.code === 'ArrowUp') {
e.preventDefault();
e.code === 'ArrowLeft' ? rotate.click() : fire.click();
}})
