Planning to exit later in the year, Kovacs said that Mozilla has achieved the goals he and his team had set. Kovacs will remain a member of Mozilla’s board of directors.

Listing down some of the achievement of Mozilla during Kovacs’ reign executive chairperson Mitchell Baker said that the non-profit organization launched Firefox OS and signed up with 20 partners to bring out smartphones loaded with the mobile OS; released Mozilla’s HTML5 app store; and created a “global, operational structure” to support market growth.

Baker said, “Gary’s leadership during this period has helped us build on the strong foundation to make these changes, and to bring that strength into the mobile environment. Gary has reinvigorated our focus on working with commercial partners, a trait that was central in Mozilla’s early life but less so during the Firefox desktop era.”

Mozilla is going ahead with quite a few other management changes in parallel – Senior Vice President of products Jay Sullivan will be now the Chief Operating Officer; Harvey Anderson has been named the Senior Vice President of business and legal affairs.
