leaving mozilla

I started contributing to Mozilla nearly 11 years ago, in 2004, and joined as a full-time employee over 8 years ago. Suffice it to say, Mozilla has been a big part of my life in a lot of ways. I’ve dedicated essentially my entire career so far to Mozilla, and it introduced me to my wife, just to name a couple.

Mozilla’s in a great place now – still a tough challenge ahead, but plenty of great people willing and able to tackle it. Firefox has new leadership, the team is being re-organized and groups merged together in what I think are the right ways, and I’m optimistic about their prospects. But it’s time for me to move on and find The Next Thing – that I have no idea what it is now is both exciting and a little bit terrifying, but I feel good about it.

It will probably take me a while to figure out what exactly a post-Mozilla Gavin-life looks like, given the various ways Mozilla’s been injected into my life. I won’t disappear entirely, certainly, and I know the many relationships I’ve built through Mozilla will continue to be a huge part of my life.

I’m looking forward to what’s next!

    You will be missed! Though, I know where to find you. 🙂 Best of luck with your new adventures.

    holy cow! we only worked together for a few months on a project- but really enjoyed working with you. You will be very missed – for your very level head and engineering skills – but just in general for being a wicked smart, great guy. Good luck and i’m sure you’ll shine in whatever you take on for your next challenge.

    Well you’ve left quite a legacy behind you and I cannot wait to see what you’ll tackle next. Any project will be the better for getting your focus and skills.

    It’s been a huge pleasure working these many years with you toward a better Web. Your contributions to Firefox and Mozilla are immense; few can claim such a long and prolific Mozilla tenure. Good luck with your next thing(s). I’m rooting for you, as I’m sure are countless other Mozillians.

    Take care,

    More than a decade of dedication; well done, sir, well done. Can’t wait to see what you get up to next.

    Although we have not met face-to-face before, I have kept tab on you for sometime. I have seen a number of your works out there & read a number of your posts many times. If my memory serves me right, you commented about my work – SIP in a web browser for multimedia services- years ago. My work has now led to the WebRTC, which is now being standardized.

    I must comment that your works also stand-out among other contributions that I have seen.
    It is natural for human to evolve i.e. to seek new challenges. Many thanks for your contributions to Mozilla.

    You will be missed Gavin.

    We both started contributing around the same time (wow, has it really been that long?), but your streak lasted way longer than mine. When I first started, I was triaging bugs and doing QA, but your work always motivated me to challenge myself and try my hand at coding. I remember thinking, “If I work hard enough, I can maybe be like Gavin in a few years.” 🙂

    Best of luck,
    Adam “ispiked” Guthrie

    I’m not going to romanticize. It’s a loss for Mozilla, I hope it won’t be one for you; hope you’ll find something you can truly care about rather than just your next career milestone.

    Wow, you really are one of those people that has left their mark on the project but if your gut is leading you to open a new chapter in your life you should always act on it.

    Whatever you do next, I am sure it will be a huge success.

    I wont miss you, it’s not like you’re dead. Sad to see you go, sad to see another awesome person moving on, best wishes to you in your next adventure.

    I just heard, and wanted to wish you good luck! You and Margaret were like the first mozillians I met in person, in Warsaw back a couple three years ago … you were wearing that purple wizards hat with the yellow stars which I thought was odd, but in a fun kinda way … when I realized you were the one who WONT FIXD my first patch that I’d written three different ways I was crushed … but I went on be further crushed by others, so you weren’t all that special … thanks for pointing out to me that technically superior people are just as plain and ordinary as I, thought they were … and that even people with no skills who can succeed like me.
