How to disable colored emoji font in Firefox?
It's not installed as a system font. The font file is contained within the Firefox directory, and deleting that one is sufficient. Note that you'll need to actually delete or move the file - simply renaming it, even changing the file extension, is not enough to prevent its use.
In the current Aurora build, the file you'll want to remove is <firefox>\fonts\EmojiOneMozilla.ttf
, where <firefox>
is the installation folder, which will vary depending on the bit-ness (Program Files
or Program Files (x86)
) and channel (Mozilla Firefox
, Aurora
or Nightly
). On Windows you can right-click Firefox shortcut and select Open file location
.

, context menu (right click) > new > string. Set font.name-list.serif.x-unicode

Colored emojis are instantaneously disabled, no need to refresh open tabs or restart the browser.
