IceWeasel
Description
In 2006, a naming issue developed when Mike Connor, representing the Mozilla Corporation, enforced their trademarks to deny the use of the name "Firefox" to the Debian Project.
The Debian Project refused Mozilla's terms and rebranded the Mozilla programs: Mozilla Firefox to Iceweasel, Mozilla Thunderbird to Icedove and SeaMonkey to Iceape. These changes are implemented in the current release version of Debian (Etch). In July 2007, Iceowl, a rebranded version of Mozilla Sunbird, was added to the 'unstable' branch of Debian.
