Software engineer Joe Hewitt has confirmed his resignation from Facebook. The developer, known for his creation of the Facebook for iPhone app and the Firefox extension Firebug, confirmed his resignation via a blog post. Hewitt spoke positively of his time working for Facebook, but halted development of Facebook for iPhone in 2009, citing problems with how Apple chose to review apps before accepting them. Hewitt says he intends to pour himself "into understanding the needs of modern developers and designers, and creating software to fill those needs". Quite how he intends to do this is unknown, but it is possible that he will develop future extensions for Mozilla Firefox to fulfill tasks, or develop fully-fledged programs.
Hewitt says he intends to become freelance in his blog post, and mentions that he has ideas for many different programs he intends to create; programs for writers, designers, and programmers. His blog"s farewell post cites his experience with the Firebug extension:
It"s been more than five years since I made Firebug, and though I stopped working on it long ago, I"ve continued thinking about it nearly every day since. It was probably the most gratifying project I"ve ever worked on. Knowing that I was helping developers solve hard problems, work more efficiently, and create awesome things gave me an energy and happiness that was unmatched.
