How to apply the fix:
If you're using Waterfox Classic or older use Stylem, if you're using Firefox 57 or newer use Stylus, if you're using Firefox 86 or newer the fonts should already be fine for you.
Paste the below CSS into Stylem and save it. If you're using Stylus, it should recognize it as Mozilla formatted code and ask you to covert it. If not, there should be a button to import Mozilla code.
Code: Select all
@-moz-document domain('discord.com') {
* {
font-family: Helvetica Neue,Helvetica,Arial,sans-serif !important;
}}
