Debian–Mozilla trademark dispute

In 2006, a branding issue developed when Mike Connor, representing the Mozilla Corporation, requested that the Debian Project comply with Mozilla standards for use of the Thunderbird trademark when redistributing the Thunderbird software. At issue were modifications not approved by the Mozilla Foundation, when the name for the software remained the same. The Debian Project subsequently rebranded the Mozilla Firefox program, and other software released by Mozilla, so that Debian could distribute modified software without being bound by the trademark requirements that the Mozilla Foundation had invoked. The new names established by Debian were Iceweasel for Mozilla Firefox, Icedove for Mozilla Thunderbird, and Iceape for SeaMonkey. These changes were implemented in the subsequent version of Debian (Etch). In July 2007, Iceowl, a rebranded version of Mozilla Sunbird, was added to the unstable branch of Debian. In 2016, a number of Mozilla employees and Debian maintainers argued that the branding was no longer needed, and on 10 March 2016, Debian's unstable branch switched back to the Mozilla branding, with the stable branch planning to switch after Iceweasel's end of life. The decade-long branding issues between the Debian Project and Mozilla Corporation ended in 2017 when all Mozilla applications in Debian were reverted to their original names. Debian's Iceweasel, Icedove, Iceowl, and Iceape were based on Mozilla's Firefox, Thunderbird, Sunbird, and SeaMonkey, respectively. The rebranded products still used some Internet-based services from Mozilla, including the Mozilla plugin finder service, and Mozilla add-ons and their update notifications. There was also no change to how non-free components, such as Flash, were found or used. SeaMonkey Iceape was a free software Internet suite based on SeaMonkey. It was developed by the Debian Mozilla Team in unison with the SeaMonkey Council's work on their release, but in accordance with Debian's policy of only using free content, copyrighted artwork and proprietary plug-ins were omitted.
