Before After

First, install the Symbola font from this page.

To handle cases where Emoji font is unspecified by page, open about:config and set font.name-list.emoji to Symbola.

However, in most cases, pages will specify a font when displaying Emoji. To handle this, install the Emoji to English addon. In the addon preferences, set the following configuration:

  • Translation display: Hide translation
  • Show emoji: Yes

Then add the following user style with an addon like Stylus or by just inserting the CSS into your userContent.css file:

.emoji-to-english-translatable{
    font-family: "Symbola";
}
