Hi everyone,

Following the Mozilla All-Hands last week, we've made the decision that Tor Browser will move from being based on the Firefox ESR (extended support release) train to the Firefox (rapid) Release train. This is a large change for us, and the decision was not made easily. We finally made this decision due to the development process of Mozilla's new Android browser (Fenix) and how we plan on building Tor Browser based on it (as well as maintaining and developing the desktop browser in parallel).

More details will become available as we make decisions about new processes and procedures. We'll announce meetings for discussing these topics on this list over the coming months.

Thanks, Matt
