input text placeholder-opacity-100 in Firefox looks lighter

[rockmandash]

Describe the problem:

Firefox default makes <input /> placeholder looks lighter, Tailwind class can't reset this behavior.

I know this is the browser default style, however, since people are explicitly saying placeholder-opacity-100, I think it should override those default style

Link to a minimal reproduction:

Code

<input
  class="w-full placeholder-red-500 placeholder-opacity-100"
  placeholder="I will look lighter in Firefox"
/>
