Firefox & Thunderbird 10.0 on OpenIndiana/Solaris with lightning and enigmail

Mozilla has release Firefox and Thunderbird 10.0 for Solaris/OpenIndiana.

But the plugins lightning for the calendar - which is a must for me - and
engimail were missing.

I attempted to compile engimail myself, but failed, because of a necessary mozilla dev environment.

But yesterday there was a post on the openindiana mailinglist, which is currently not in the archive, which located new compiles for lightning and
engimail for Firefox and Thunderbird 10.0.
