dotted outline coming for </button><button> tag in firefox

Question

On focusing of the <button> tag, I'm unable to remove dotted border around its text.

I tried

border:0, outline: 0 

properties. These properties only remove border and outline from <button> but border around text comes on focusing of button.

这可能就是你要找的东西：

button::-moz-focus-inner {
  border: 0;
}
