Mozilla promoted Brendan Eich to CEO — a 2008 donation surfaced and he lasted 11 days

On 24 March 2014, Mozilla's board appointed Brendan Eich — a co-founder of the project, creator of JavaScript, and CTO — as its new CEO. The choice looked like a promotion from within that would preserve the organisation's engineering culture.

Within days, a 2008 donation by Eich of $1,000 to Proposition 8, the California ballot measure that banned same-sex marriage, resurfaced publicly. Mozilla employees and open-source contributors called for his resignation. Dating site OkCupid displayed a message to Firefox users urging them to switch browsers. The controversy dominated the press around a company that had long presented itself as mission-driven and inclusive.

Eich initially refused to step down and said his personal beliefs were separate from his role. Mozilla's executive chairwoman issued a blog post defending the organisation's commitment to inclusivity while also supporting Eich. The position satisfied no one: staff continued to object and partners distanced themselves. On 3 April 2014, eleven days after his appointment, Eich resigned from Mozilla entirely.

The $1,000 donation to Proposition 8 cost Mozilla its CEO in 11 days, plus leadership and reputation damage.

The board promoted a public-facing CEO without stress-testing how a prior political donation would land inside a values-driven organisation and its community

The $1,000 Prop 8 contribution was a matter of public record; once surfaced, it became a proxy for Mozilla's stated commitment to openness and inclusion

Mozilla employees and external contributors treated the appointment as a referendum on the organisation's values, not merely its leadership competence

The board's attempt to separate personal belief from institutional role failed because the CEO is the public embodiment of the organisation's values

For a values-driven organisation, a CEO's public record is part of the hire. Personal beliefs that conflict with the organisation's stated identity will be treated as institutional positions.

Eich left Mozilla and later founded Brave, a privacy-focused browser. Mozilla appointed Chris Beard as interim CEO and conducted a public review of its hiring and governance processes. The case became a standard reference in discussions about the separation of personal and organisational identity in leadership appointments.
