It's a very sad day when the open-source community is forced to take a highly-successful, visible, driving project like Firefox and change its name to something like Iceweasel. By changing the name we lose invaluable branding and popularity for the Debian and other distributions that choose to make this distinction. This sort of decision is equivalent to a 3 year regression for Linux.

The name Iceweasel sounds like the odd name of an infant open-source project. Many people give up on Linux read names like Iceweasel and GIMP.
