Hi,
until now, we've been shipping the latest iceweasel (-release branch),
because it was the only relatively cheap way for us to get a "recent
enough" iceweasel for Tails needs.
Debian Wheezy will ship with iceweasel "Extended Support Release"
instead:
  
https://www.mozilla.org/en-US/firefox/organizations/faq/
  https://wiki.mozilla.org/Enterprise/Firefox/ExtendedSupport:Proposal
Currently, that release branch is available in mozilla.debian.net's
Squeeze (iceweasel-esr) repository, and in Debian sid (currently,
that's 10.0.3esr-2), while the -release branch (currently, that's
11.0-2) is in Debian experimental.
I think we should do the same as Debian Wheezy.
Deciding to follow the -release branch instead would have a few
drawbacks for us:
 - continuously need to wait and cherry-pick updated add-ons from sid
   (as we've been doing for a while, breaks the build process more
   often than not)
 - no security support from the Debian security team
 - more work to get a new iceweasel, that fixes this or that serious
   security issues, integrated into Tails, due to the need to do
   a major iceweasel upgrade => more days of exposure to security bugs
   for Tails users
Thoughts?
Cheers,
