Font gone funny after Windows update

This morning when I got into the office my computer had been rebooted due to a Windows update. When firefox loaded up I noticed that the font had changed and in some instances was nearly unreadable.

I find Google Plus to be a good example of this: http://imgur.com/gw6308F

This support website also seems to have problems.

Did you get a new version of IE today?

It appears you already have disabled Firefox's use of hardware acceleration for graphics here:

orange Firefox button (or Tools menu) > Options > Advanced > General mini-tab > (uncheck) "Use hardware acceleration when available"

Next, try disabling the azure technology.

(1) In a new tab, type or paste about:config in the address bar and press Enter. Click the button promising to be careful.

(2) In the search box above the list, type or paste gfx and pause while the list is filtered

(3) Double-click the gfx.content.azure.enabled preference to switch it from true to false. I can't recall whether the change takes effect immediately, or after you exit and restart Firefox.

I don't think I've got a new version of IE. I have been running IE11, so it may have updated.

I don't see a gfx.content.azure.enabled in about:config. I added a new boolean and set it to false, but it hasn't helped (even after restart). I can see gfx.content.azure.backends in about:config, should I be editing that?

Sorry, I still run Firefox 26 and am not familiar with what has happened with Azure in Aurora.

If your gfx.content.azure.backends preference looks like: 

direct2d,cairo

Try deleting direct2d so you just have 

cairo

The idea is to prevent Azure from going directly to your GPU, hopefully working around any graphics card driver-based conflicts. Any change?

I tried deleting direct2d in gfx.content.azure.backends but that hasn't helped. I also tried deleting it from gfx.canvas.azure.backends, but it doesn't look it helps either.

That's troubling. Maybe Firefox will no longer be usable on Windows 7 after everyone is forced to accept the latest IE 11?

This article recaps the problem: 'Blurry fonts' bug KB 2670838 persists with IE11 and Windows 7 | Microsoft windows - InfoWorld.
