Package: firefox
Version: 52.0.2-1
Severity: important
Tags: patch upstream
Dear Maintainer,
PowerPC (and presumably all other big-endian architectures) suffer a severe
performance blow on account of an endian-ness problem in ARGB/RGBA support.
Messages such as:
`Crash Annotation GraphicsCriticalError: |[0][GFX1]: Unknown image format 1
(t=20.0634)`
get spammed to the console at an alarming rate while using the browser.
It appears that this is because of a problem introduced by the fifth attached
patch in Mozilla (not Debian) bug #1209812 - "Add endian-neutral variants to
SurfaceFormat."
https://bugzilla.mozilla.org/show_bug.cgi?id=1209812
In particular, using the part under the `#if MOZ_LITTLE_ENDIAN` preprocessor
block for all cases (removing the big endian case and the preprocessor guard
for the little endian one) appears to fix the problem.
This is my first time reporting a bug in Debian, but if I've done this right
a patch should be attached which fixed it for me and probably also fixes it
for other big-endian platforms. I noticed a marked performance increase after
applying this patch as well - probably due to not writing a ton of error
messages to the console anymore. I have noticed no averse impact so far.

Thanks. It looks like that has got silent, hopefully the issue got fixed in
newer versions.
Cheers,
