Some fonts used by Google are rendered with incorrect letter spacing
Hi, looks like Firefox has some trouble displaying some fonts used by Google. The font used in the Google's about page, Gmail or the Google's sign-in page looks horrible. I'm not a font expert but it seems like it's the same font across all the three sites I've just mentioned. I've immediately noticed that Firefox has a different way of rendering fonts on the page, compared to Chrome (just recently made the switch), but most sites look fine despite the minor differences; the only exception being many sites made by Google.
For a better understanding of the problem, I took some screenshots (https://imgur.com/a/1lHu01S) of two pages rendered by Firefox and Chrome.
P.S. I'm using Archlinux with the latest version of Firefox.
