He suggested renaming the Mozilla Corporation to the Firefox Corporation and pointed to a newsgroup message in which Mozilla Corporation CTO Brendan Eich declared 'Thunderbird will have to fly free'. In April, former Firefox lead developer Ben Goodger wrote a weblog post discussing autonomy for non-Firefox projects. Observers of the Mozilla community may have seen Thunderbird's new home coming. Scott explains that this means that Thunderbird would continue to use Mozilla Foundation infrastructure, such as the CVS repository and Bugzilla, and the new company would perform a similar role for Thunderbird as the Mozilla Corporation does for Firefox, developing, releasing and supporting the application. He states that he favours the third option. On his new weblog, lead Thunderbird developer Scott MacGregor has posted his thoughts on the finding a new home for Thunderbird.

However, there are concerns over how the Thunderbird product, project and company would interact. A final option is to recast Thunderbird as community project, similar to SeaMonkey, and set up a small independent services and consulting company to continue development. A second option is to create a new subsidiary of the Mozilla Foundation for Thunderbird, which would keep the Mozilla Foundation involved but may mean that Thunderbird continues to be neglected in favour of Firefox. One is to create a entirely new non-profit, which would offer maximum independence for Thunderbird but is organisationally complex. Mitchell outlines three possible options for a new organisational structure for Thunderbird. The resources allocated to Firefox dwarf those allocated to Thunderbird and recent projects such as the initiative to improve Mozilla support exclude Thunderbird. However, it has become increasingly clear that Firefox is the priority. While the Mozilla Foundation supports a number of projects, its taxable subsidiary the Mozilla Corporation is responsible for only Firefox and Thunderbird.
