After a bunch of work the last couple of days, I think we’re in a much better place with respect to notices & licenses for Firefox. Harvey has posted proposed changes to the presentation of notices, as well as to the content of notices, and they’re better than before, by a long way.
Canonical/Ubuntu has worked with us on this a lot, and has been very helpful, as have the RedHat and Fedora teams.
This should make its way into all our platforms and builds at some point in the near future, and should make things better for all users.

Sweet! This will make it significantly easier to download Firefox nightlies on Leopard, especially with Safari. Instead of (wait, click agree, wait, drag) it will just be (wait, drag).
