Excited by bug 561361 comment 7, I went to try it out myself. Unfortunately, all I got was a crash :-(

This was with a new profile and gfx.azure.enabled = true.

Loading https://github.com/mojombo/ernie/network crashes almost immediately. I also see in the terminal:

--- no context for glyph 2f
--- no context for glyph 52
--- no context for glyph 44
--- no context for glyph 47
--- no context for glyph 4c
--- no context for glyph 51
--- no context for glyph 4a
--- no context for glyph 3
--- no context for glyph 55
--- no context for glyph 53
--- no context for glyph 4b
--- no context for glyph 57

So HarfBuzz seems to be having some trouble. Interestingly I haven't found another page that crashes yet, not even wikipedia.org which is typically font intensive because of all the different languages on the homepage.

First crash (also had layers.acceleration.force-enabled = true):

bp-72326c88-c574-4fbb-ae67-558a42120201

and without layers.acceleration.force-enabled (to rule it out):

bp-b260e484-3c22-47e0-a1cd-3a36a2120201

Graphics

Adapter Description: NVIDIA Corporation -- GeForce GT 520/PCI/SSE2
Vendor ID: NVIDIA Corporation
Device ID: GeForce GT 520/PCI/SSE2
Driver Version: 4.1.0 NVIDIA 280.13
WebGL Renderer: NVIDIA Corporation -- GeForce GT 520/PCI/SSE2 -- 4.1.0 NVIDIA 280.13
GPU Accelerated Windows: 0
AzureBackend: skia

Let me know if there's anything I can do to help test this.
Skia is only used for canvas elements for now, so it can crash only when in the page there's a canvas (this is why on Wikipedia it doesn't crash).
However, this bug should be strictly related to bug 723110, I don't know if it's a dupe.

The site from description crashes for me too. In addition to this I found some sites with the same problem (as I suppose):
http://canvasrider.com/tracks/random
http://ie.microsoft.com/testdrive/Performance/FishBowl
http://ie.microsoft.com/testdrive/Performance/Paintball/Default.html
http://www.sinuousgame.com

I think it may be helpful in testing and searching the cause of the problem.
Thank you for your testing, I think the cause of the crashes is a problem in the font handling.
Could you try compiling a custom build with the patch in bug 723110 and see if the crashes are still there with that build?
Yes, I've compiled firefox with this patch and every webpage from the list I posted above runs without any crashes.
