Does anyone know what `font-feature-settings` does? ProtonMail and GitHub both use this setting and it causes fonts to display weird in Firefox.

It changes different settings in the font. In GitHub's case, they use the font "Alliance No.1". ss02 doesn't appear to have a visible effect, but ss01 changes the letter a from a rounded body with a stem on top to a rounded body with a straight stem on the right. You may have custom fonts disabled—these feature settings do the right thing on GitHub's and ProtonMail's ("Arizona") fonts, but make your system fonts do weird things. Both sites appear just fine for me on Firefox on Linux.

Ah. I forgot I turned that setting off years ago. I guess the Firefox account saves settings.

Just need to figure out how to disable that css option.

Thanks for the info!
