When you have a Form (Remix) whith a <button type="submit" disabled={disabled}>, Firefox results in hydratation error Prop 'disabled' did not match. Server: "null" Client: "true".

To solve this issue, just add autoComplete="off" on your Form

const [isDisabled, setIsDisabled] = useState(false);

// ...

<Form method="post">
  {/* ... */}
  <button type="submit" disabled={isDisabled}>Continue</button>
</Form>
