Hi!
Thanks for being part of the Font Awesome Community.
Sorry, I cannot replicate
Could you please provide more information on your browser / OS?
That is true.
Firefox OK, Safari OK, on Chrome 70.0.3538.77 and 70.0.3538.102 on macOS is not.

DOM element without ::before css selector...
(the first one, with :: before, is working. The other one is not)

But this issue is NOT only on fontawesome website, it is on my app as well:
webpack4
@fortawesome/fontawesome-svg-core" LAST VERSION
@fortawesome/free-brands-svg-icons LAST VERSION
@fortawesome/pro-light-svg-icons LAST VERSION
@fortawesome/pro-regular-svg-icons LAST VERSION
@fortawesome/pro-solid-svg-icons LAST VERSION
@fortawesome/react-fontawesome LAST VERSION

macOS 10.14.1 / Chrome 70.0.3538.77

and Chrome 70.0.3538.102

could you please
Sorry, my fault
I forgot that I use a chrome extension called "Shut out", that remove no constructive comments on youtube and news sites. It looks like that last update started to remove comment icon from fontawesome as well.
@maxguzenski thanks for the heads-up
