::-moz-progress-bar

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The ::-moz-progress-bar CSS pseudo-element is a Mozilla extension that represents the progress bar inside a <progress> element. (The bar represents the amount of progress that has been made.)

If you want to select the unfinished part of <progress> in Mozilla, please select the <progress> directly.

::-moz-progress-bar {
  /* ... */
