Firefox's developers really like the Direct2D api because it is so easy to use. "
Says who?
The OpenGL functionality was first. Lately the Firefox developers have added the yet-to-be-fully-debugged option of using Direct2D instead (this is not enabled by default) only to the Windows version of Firefox because OpenGL performance is abysmal on many Windows systems compared to what it should be.

ATI has enabled their closed source Linux driver to use some of the same internal code for 2D acceleration as their Windows Direct2D driver. The Linux driver APIs remain unaffected, and there is no actual Direct2D API implemented in Linux (other than a partially-working dll in Wine).
With some luck, this improvement may eventually reliably bring ATI's closed driver Linux 2D performance up to almost the level of 2D performance of the ATI OSS drivers. There have been some positive reports based upon the vast feedback in forum threads, while others are experiencing problems like the driver not even working.

Which Firefox does via using the OpenGL graphics API, since almost all smartphones don't run Windows, and the Direct2D API is Windows-only.
