FF53.0.2 - font spacing weird after update

I updated to 53.0.2, and all of the sudden the font spacing is weird. It's not even consistent - it's not like font spacing is consistently condensed or expanded, it's all over the place. It looks like OCR'd text, if anyone has ever seen a Word file extracted from a PDF. It's all over the place.

Suggestions?

This could be related with the recent switch in Firefox 52+ from Cairo to Skia for canvas/content rendering.

Firefox 52+ has changed from Cairo to Skia for canvas/content rendering.

You can modify these gfx.*.azure.backends prefs on the about:config page to revert to the old font rendering swap the skia,cairo order to cairo,skia or remove the skia and leave cairo.

  • gfx.canvas.azure.backends = direct2d1.1,cairo,skia
  • gfx.content.azure.backends = direct2d1.1,cairo,skia

You can open the about:config page via the location/address bar.

You can accept the warning and click "I'll be careful" to continue.
