You mean like this <https://i.imgur.com/6ZXAchD.png>? You can get the old look back via userChrome.css. Relevant styles from mine:

  #PopupAutoCompleteRichResult .ac-separator {
    page-break-before: always;
    width: 47px;
  }

  #PopupAutoCompleteRichResult .ac-separator-text {
    display: none !important;
  }

  #PopupAutoCompleteRichResult richlistitem {
    display: flex;
    flex-wrap: wrap;
    align-items: center;
    height: auto;
    padding-bottom: 5px;
  }
