Firefox Browser Architecture


Change Mozilla. Investigate big technical challenges and produce engineering programs to address them.

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.
