Hello, I am seeking to get the latest version of Mozilla Thunderbird approved on my employer's enterprise. There is currently a big push to support American products so my job requires confirmation of Country of Origin, ie an official document or letter, from the software company to provide proof that any software requested is sourced from either the United States or friendly partners (https://gsa.federalschedules.com/resources/taa-designated-countries/) If someone from Mozilla could provide an official letter to me confirming that Mozilla products are primarily developed and/or transformed in the US or its partners that would greatly appreciated as no new software will be approved without this. Please feel free to reach out to me if you have any questions or concerns. Any document you provide can be emailed to sean.m.lee8.civ@mail.mil.
