Re: [EXPLAINED] iceweasel 3: favicon while tab is loading

Hi,


In sid's iceweasel 3 I notice a difference with iceweasel 2:

when a tab is loading the favicon shown would slowly rotate in version 2, but in version 3 it stays stuck at the beginning.

Searching bugzilla.mozilla.org I find nothing under "favicon", but it clearly is a visible but minor bug.

Anybody else notice this behavior?



I filed a bug:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=487411

It was answered right away by Mike Hommey:

The most probable reason is that the new icon is an APNG, which iceweasel 3 doesn't recognize, while firefox does. APNG is a torture of the PNG standard, that was rejected by the PNG group, and official libpng is probably not going to include APNG support for a while. Firefox uses a bundled and heavily patched libpng, which we can't for maintenability reasons.

So that explains it.
