J. Healy.[12] Later Siminoff moved to Senior Vice President of Entertainment and Small Business, with Toby Coppel and Jeff Weiner taking over corporate development.[13] Six months later, Yahoo announced on April 13, 2002, that Siminoff decided to leave the company in order to spend more time with family, and would stay through until the end of the year.[14][12] Her departure was part of a high-profile exodus of Yahoo executives, including CEO Timothy Koogle, CFO Gary Valenzuela, sales chief Anil Singh, head of international operations Heather Killen, and marketing head Karen Edwards.[14]

Mozilla

On March 24, 2014, Siminoff and two other board members of the Mozilla Corporation resigned from the board in advance of Brendan Eich's appointment as CEO of Mozilla.[20][21][22] Eich was noted for his donation of $1,000 to California Proposition 8, which called for the banning of same-sex marriage in California. Eich resigned from Mozilla 11 days later, on April 3, 2014.[23][24]
