Firefox Browser Architecture


Build the world’s best web browser


Our top priority is to plan for where we want to go, but if we just think 5 years out, we’ll miss the dragon on the doorstep. So we need to look from both angles:

  1. Look forward from where we are now: Move faster
  2. Look backwards from where we want to get to: Consciously plan our architecture

Our Conclusions

This is a list of our findings that we’re reasonably happy with so far.


We typically send our newsletters to firefox-dev.

Explorations and Experiments

To support our conclusions we occasionally perform explorations and experiments. The first exploration is designed to support the notion that we can create a sync and storage layer in Rust that we can deploy to Desktop, Android and iOS.
