FOSDEM 2020 - Call for Proposals

Mozilla devroom: Call for papers

Hello fellow Mozillians,

It’s that time of the year again! The Call for Papers for Europe’s largest FLOSS event, FOSDEM, happening on February 1st & 2nd 2020 in Brussels is now officially open.

Just like for the past 15+ years, Mozilla is going to host a Developer room at FOSDEM 2020 for a full day and we would love to see and hear all your wonderful talks.

For those of you that have no idea what FOSDEM is about, I recommend taking a look at their website (

Developer rooms are assigned to self-organising groups to work together on open source projects and to discuss topics relevant to a broader subset of the community.

Proposals should not be limited to the list but those that are stand a higher chance of getting accepted. However, we do encourage you to submit talks on subjects that are not on the list, some of our best talks were on subject we did not expect at all.

However, please keep in mind, that the public at FOSDEM is quite technical and knowledgeable about open-source in general.

If you want any help or feedback to write your proposal, please get in touch with me and I am happy to but you in relation with someone that can help you to perfect your proposal or give you a useful feedback.

The list of preferred topics is the following:

  • Web Technologies: HTML, CSS & Layouts
  • WebVR
  • WebAssembly
  • MDN Web Docs
  • Firefox Developer Tools
  • Privacy & Security
  • Performance
  • Network on Web browsers
  • MOSS
  • Diversity & Inclusion

Essential infos:

Hello everyone,

Thanks to better planning this year, we have 2 extra week of time for people that would like to propose a talk to our CFP.

If you were late or forgot about us now is your chance! If you are not sure it would be “good enough” or if it’s your first time, please propose anyway and shout me an email, we can provide assistance to write or fine-tune your proposal.
