Johnathan Nightingale, Mozilla's vice president of Firefox, has announced that he will be leaving the company on March 31. He said that the move will not only help him spend more time with his family, but will also allow him to plant deeper roots in the Toronto tech scene.

In a note sent to employees, Nightingale emphasized that the company today is stronger than ever and the web browser is in a good place. However, he also said that the decision will definitely raise questions and bring out the trolls.

"When this news gets out, I imagine someone will say something stupid. That it's a Sign Of Doom. Predictable, and dead wrong; it misunderstands us completely," he said, adding that he was with the company during tough times, for example, at the beginning of 2014.

Although Nightingale tried his best to downplay his departure, there is no denying that the move will raise eyebrows given that the company has already seen a lot of management changes in the recent past.

Back in March last year, Mozilla's year-long search for a new CEO ended with the appointment of JavaScript creator Brendan Eich, who was promoted to the position from CTO. However, he stepped down just days later after people (including Mozilla employees) voiced their disapproval over the fact that he donated $1,000 to support California's Proposition 8 campaign against same-sex marriage back in 2012.

A few months later, the company announced interim CEO Chris Beard as its permanent chief.
