Comment 4 for bug 376155

#3 Helder,

from what I remember in May...

recent builds 'claim' support for SMIL, even though this is partial.
I proposed removing SMIL support claim whilst support is partial, this was rejected.

the responsible developers believe there efforts are best directed to completing support asap
in the meantime fakesmile is disabled, due to 'claim'

end result is sites remain broken in the interim.
this could be days, weeks, months or years.

regards

tested links today with latest nightlies on OS X ppc and can confirm this is the current status to the best of my knowledge.
