Mozilla chief executive Gary Kovacs has announced his intent to step down from the company, after two and a half years leading the open source web browser maker.
In an interview published by AllThingsD, the Mozilla boss said that he was looking for a career change and would be leaving the open source browser pioneer.
"After three years of a lot of change to move the organisation faster forward, I wanted to move back to something more commercial," Kovacs was quoted as saying.
Kovacs was appointed to the chief executive role with Mozilla in October of 2010. Over that run, Kovacs helped to push the browser forward in an increasingly competitive market.
While the browser has maintained a respectable position in the market, Mozilla has been unable to push its market share beyond the 25 percent mark, as competition from Google's Chrome has intensified.
Firefox has also failed to make major inroads on the growing mobile browser market. While rival browsers such as Chrome and Safari have made their mark by anchoring the Android and iOS platforms respectively, Firefox has yet to make a same for itself in the mobile market.
In an employee letter published by Engadget, Mozilla's outgoing chief urged the company to keep up the fight for open source products.
"We have momentum, we have a great vision and mission, and we have tremendous support from all of our partners and users for what we are doing," Kovacs said.
"We cannot let up - not for one second. Stay focused, keep going, and keep rocking the free Web."
