firefox extension auto updates

[coypu%SDF.ORG@localhost]

Hi,

It turns out that firefox will auto-update for extensions daily (the one
from pkgsrc, too).

We generally disable the auto updating of programs (libreoffice, firefox
etc all have the ability). should I look for a way to disable this
option by default, too? it's a single config flag -
'extensions.update.enabled'.

Is this something we want to do?
