Any solution to remove clear button <input type="time"/> on Firefox?

Question

I tried to disable-hide the clear button and didn't work for Firefox.

But on Chrome, Edge, Safari it works fine. Any idea why? Is there a solution?

Following is the CSS:

input[type="time"]::-webkit-clear-button {
  display: none;
}

See the Image of output

Answer 1

<input type="time" required> hides the reset button.
