2-8-18 My computer did a windows update, and my firefox did an update. Since all the text on my firefox is grainy, and weird looking. I wouldn't care but it is hurting my eyes to look at it. I've looked for answers on your support page but I'm not coming up with anything that is working. Please help me. I work from home with my firefox and I've always loved it. But this is not going to work.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

No that did not do anything. Attached is a screen shot of my screen. Logo's and photos are working fine. But the text on any website, typed, anything all look really strange. Grainy. "l, B, N, M, T," examples if you look anything that has a line has a double line in the points. I'm really confused.

Nope that was already checked. Didn't fix anything.

You can check that you do not run Firefox in compatibility mode. You can open the Properties of the Firefox desktop shortcut via the right-click context menu and check the "Compatibility" tab. Make sure that all items are deselected in the "Compatibility" tab of the Properties window.


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 to see if that has effect.

  • 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 accept the risk!" to continue.

If this didn't work then undo/reverse the change and reset the prefs you modified via the right-click context menu to the default value.
