I have seen this in today's nightly too (win32 build, Win 8.1 x64, All D2D1.1/DX11 stuff active, Nvidia GTX650, latest drivers).
Tracking for 40. 

Florin, can you have a look to see if this regression also affects 38 and 39 since we uplifted the patch in bug 1150376?   We may just end up backing out that patch.

This doesn't look "blurry" to me, it just looks like the text hinting is different.  Likely due to different rendering mechanism in use (no D2D/DWrite after the patch maybe?)
I talked to Bas about this. We're going to change this so that it only happens when using WARP.

It seems that 38 and 39 are not affected by this issue.

Tested on Windows 7 64-bit with:
- latest Aurora, build ID: 20150416004008;
- Firefox 38 beta 5, build ID: 20150416143048.

On my machine this issue is like some characters is "broken". Windows7 and firefox nightly v40 x64 edition.

Only use Basic OMTC when using WARP.
