Iceweasel is a fork [from Firefox] with the following purpose :

  1. backporting of security fixes to declared [:DebianStable:Debian stable] version.

  2. no inclusion of trademarked Mozilla artwork (because of #1 above)

Beyond that, they will be basically identical. (quoting Roberto C. Sanchez post in [http://lists.debian.org/debian-devel/2006/10/msg00665.html debian-devel] mailing list)

Also note that iceweasel is NOT Iceweasel from [http://www.gnu.org/software/gnuzilla/].

In DebianEtch and DebianSid the name of the package is [http://packages.debian.org/iceweasel iceweasel] (a transitional [http://packages.debian.org/firefox firefox] package exists).

Invoke it using one of this ways:

 /usr/bin/iceweasel

 /usr/lib/iceweasel/iceweasel

or simply

 iceweasel

For ["Gnome"] launcher, use

 /usr/lib/iceweasel/iceweasel "%s"

to open a concrete page.
