User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.42 Safari/537.36

Steps to reproduce:

1. Open Firefox on macOS Mojave.
2. Navigate to any site, preferably with a lot of text like Wikipedia.
3. Open the same web page on 1) Safari or 2) Firefox on an older version of macOS.
4. Compare the font antializing.


Actual results:

Web pages look like `font-smoothing: antialiased` forceably applied.


Expected results:

Texts should not be antialiased.

Talked with Jonathan Kew. It seems like Apple is still tweaking things behind the scenes related to this, to the extent that we won't know the full impact of this until 10.14 is actually released or gets closer to release.
