Using Google Chrome unstable (latest) and Firefox 52.0.2 on Stretch with MATE.
Fonts have always looked better in Firefox than in Chrome, no matter the version I have used.
What is needed to force Chrome to look better.
I'm not talking about the UI fonts, as Chrome does not seem to use GTK3 yet. I can control the UI with styles in my themes.
I'm talking about how ugly the fonts look on rendered Web pages.
Here's a comparison. Firefox looks great to me but Chrome looks horrible.
