Open this canvas demo (bouncing balls) of paper.js: http://paperjs.org/examples/bouncing-balls/ Click with the mouse pointer to add 4-5 balls. You can use about:memory or the OS process manager to control the resident memory use. Result: With HWA on, the resident memory use increases immediately and quickly (in 5-10 sec) to the max (in my case, it was > 2GB). With HWA off, the memory use is normal (slight increase). NB: In both cases, there is visible peak of CPU charge during the canvas animation. I tested with various versions and I found this increase of the memory use appears with the implementation of the Direct2D Azure Backend in FF7.

I don't know if it's related, but in addition to the memory increase, I get some slowdowns, the canvas becomes blank momentarily, and if I try to change tabs during these problems the browser tabs lose their background (gradients?). http://i.imgur.com/otYiC.png
This sounds similar to bug 767337. Nick Cameron, can you take a look? Or maybe Bas, if it's an Azure thing?
Whiteboard: [Memshrink] → [Memshrink:P2]
I had a quick look at this and I am pretty sure it is the same as bug 767337 - I can't reproduce the excessive memory use, because the fix for 767337 cures my setup, but not Loic's, so that fits. And the test case uses lots of gradients, which is the same source of excessive memory use as 767337.
