[regression] Text rendering is incorrect
Those three operations should make the text rendering correct:
Disable hardware acceleration Set gfx.canvas.azure.backends to direct2d1.1,cairo Set gfx.content.azure.backends to direct2d1.1,cairo
Dark theme can be tested by reversing the foreground and background colors in the HTML.
For reference, here is the correct GDI rendering of this website:
In Firefox ESR 52.4.1 (32-bit), text renders correctly:
which is the same as the GDI rendering of this website, except for some line spacing issues.
However, in Firefox 70.0b6 (32-bit), the rendering regressed and text no longer renders correctly:
Line spacing is correct, but don't let this distract you from how profoundly unsmooth the rendering is in the light theme version. The dark theme version is nearly identical though.

If you disabled HA, enumerating 'direct2d1.1' was redundant. You've been using cairo for text rendering.
Recently cairo code has been removed from the browser. See bug 1517077.
What a facepalm it is that high quality text rendering has been removed. It is a regression. It is a dealbreaker because many if not most webpages have text in them so I'm not using the recent version.
See this Reddit thread :
Has anyone tested whether this regression is crossplatform? (all platforms using Mozilla's open-source DirectWrite renderer as opposed to the system native text rendering engine)
