>Description:
firefox-29.0 and various previous versions incorrectly display orange and blue colours, i.e. those colours are swapped. You can see the effect on the following screenshot:

https://drive.google.com/file/d/0B5_0Y3a5LFU8ZEhaOFh4V3FENlE/edit?usp=sharing

The following observations have been made:

1. The issue seems to occur on sparc64 with Creator3D UPA framebuffer (ffb0 at mainbus0 addr 0xfebc0000: Creator3D, model SUNW,501-4788, dac 10)

2. Someone has tried running the same firefox binary package on sparc64 but with a PCI graphics card and the issue was not reproducable.

3. The issue is not reproducable if I enable X11 forwarding and ssh into sparc64 machine from x86, then executing firefox on sparc64, so that it is displayed on x86.

4. It is only firefox binary that shows the issue on sparc64. Other GTK programs on the same machine display the same image correctly.

It seems like a big/little-endian bug in firefox that only shows up with Creator3D framebuffer, or maybe there is an issue with X11 ffb driver??
>How-To-Repeat:
Run firefox on sparc64 with Creator3D framebuffer.

 Moved categories so it has a better chance of being resolved
 in case the problem still exists. it doesn't sound like a firefox
 problem, too.
