Mozilla co-founder CEO Brendan Eich, who came under fire this week for donating to a campaign to ban gay marriage in California, has resigned.
Eich, who became the CEO of the nonprofit company behind Mozilla Firefox on March 24, had donated $1,000 for the successful Proposition 8 ballot measure that passed in the November 2008 state election.
Eich was previously chief technology officer of the company, but had been involved in Mozilla's development starting from its conception in 1998. The previous acting CEO Jay Sullivan had left the company to pursue "new opportunities," the company said.
After the announcement that he would become CEO last week, some Mozilla staff protested his appointment while three of Mozilla's directors resigned. OKCupid protested by refusing to allow users to run the dating website with the Firefox browser.
