When
AOL (Netscape's parent) drastically scaled back its involvement with Mozilla Organization, the Mozilla Foundation was launched on July 15, 2003, to ensure Mozilla could survive without Netscape. AOL assisted in the initial creation of the Mozilla Foundation, transferring hardware and intellectual property to the organization, employed a three-person team for the first three months of its existence to help with the transition, and donated $2 million to the foundation over two years.
In September 2019, the Mozilla Foundation,

In November 2017, Mozilla terminated its agreement with Yahoo two years earlier than planned. While numerous factors were attributed to the decision to terminate the agreement, including some mention that Mozilla saw declining revenues related to the switch, likely the impetus was related to the recent acquisition of Yahoo by Verizon and Oath. Per Mozilla Chief Business and Legal Officer Denelle Dixon, "We exercised our contractual right to terminate our agreement with Yahoo! based on a number of factors including doing what's best for our brand, our effort to provide quality web search, and the broader content experience for our users. We believe there are opportunities to work with Oath and Verizon outside of search."
