- Prioritise getting the new extension framework fully functional. And continue innovating on the capabilities that are exposed. Especially on mobile where the new fenix engine is still limited to a small whitelist of extensions
- Sort out the multi-profile story. Container tabs are great, but the chrome model is also a great fit for many workflow (e.g. different people in a house or home vs. work profiles).
- Try and work on making Gecko easily embeddable again. Webkit/Blink gets all the attention because it's easy to embed into things. I suspect Gecko needs to compete in this market if it hopes to survive. It needs to have more than one company invested in it.
This ship has probably sailed now as they've fired most of their Rust and Servo teams. But IMO they ought to have created a rust-based cross-platform UI framework. They tried to do it web-based with Firefox OS but that was too slow. But with a Rust solution I think they could have owned both the mobile and desktop application spaces, which could potentially have made them a bootload of money and been a huge win for linux.
