FOSDEM 2021 - Call for Proposals

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 6th & 7th 2020 in Brussels on the Internet is now officially open.

For those of you that have no idea what FOSDEM is about, I recommend taking a look at their website ( and parse some memories down the lane with #mozdem on different networks.

Just like for the past 19 years, Mozilla is going to host a Developer room at FOSDEM 2021 for a full day and we would love to see and hear all your wonderful talks.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.

We have a list of suggested topics that we would like to hear from this year, but we encourage you to propose talks on other subjects if you believe they would be a good fit. Some of our best talks were on topics we didn’t think about.

One first tip for applying is to 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. I am happy to put you in relation with someone that can help you to perfect your proposal and/or give you useful feedback.

The list of suggested topics is the following:

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

Essential infos:

  • Submit your proposal on Pentabarf ( , you can find a tutorial about how to use Pentabarf courtesy of the wonderful folks at the Go Devroom (
  • Talk proposals deadline: 31st of December at midnight (anywhere in the world).
  • Acceptance/rejection notice: At the latest for the 7th of January.
  • Duration: 15 to 45 minutes talks (including questions) would be preferred, anything over 45 minutes and we might ask you to shorten it to fit in the 45 minutes time frame.
  • The online format is different this year. You need to be able to pre-record (which implies to have appropriate equipment to do so) your talk till the 21st of January and be available on the 7th of February at the time of your talk broadcast to answer questions.
  • If you encounter any issues with the proposal tool, please get in touch with me!
