About me

Hi there! I’m David Tenser and I work at Mozilla as the Director of USA (User Support & Advocacy). As such, I’m responsible for Mozilla’s global and open source support platform and community at support.mozilla.org, also known as SUMO. Mozilla has been my hobby since 2001 and I still need to pinch myself sometimes to really believe that my hobby is my full-time job. For up-to-date news about SUMO, check out the SUMO Blog.

Aside from being a big fan of Mozilla, I’m also a computer scientist and a passionate believer in open source. My first contribution to open source was made in 1996 when I wrote Battleship on my TI-82 calculator, proudly written in Basic and quickly spreading to fellow students of my school.

I live in Eskilstuna, Sweden with my wife Sophie and our 16 (!!) year old cat Tiger. I love scuba diving and photography. Most of my photos can be viewed on Flickr.
