As mentioned in #756, RU AdList CSS Fixes uses CSS styles to hide elements without the site noticing:

Transform and opacity combined with position:fixed and negative left-top coordinates are primarily used as alternatives to display:none when site checks visibility of ad blocks. Transform:scale(0) is especially amazing at that.


@-moz-document domain("")
  .b-layout__col_2_2 > style + div[id][class], 
    .content__left > style + div[id]:not(#breadcrumbs)
    transform: scale(0) !important;
    opacity: 0 !important;
    position: fixed !important;
    top: -1000px !important;

What to change

  • Add alternative methods for hiding elements in addition to display: none
    • position: fixed; left: -10000px; top: -10000px;
    • opacity: 0
    • transform: scale(0)
    • visibility: hidden
  • Provide filter authors with the ability to specify one or more hiding methods
