[Pkg-mozext-maintainers] Bug#739023:

[Milan Kostić]

"I'd welcome a confirmation of the issue before asking for a stable-update."

 Version from stable (0.9.20) worked here... but i think people maybe
having issues with blocked mixed context which is enabled by default
from iceweasel 23 onwards and needs to be disabled  for many scripts
to work :).
