@sarahjamielewis While it is understandable why TB/MB stable uses ESR via base browser, ESR is a meme. Considering Firefox is already behind in security compared to Chromium, using ESR, which does not receive all the security fixes that the regular release does, makes it worse.
I suggest TB base as a starting point only because it already exists as a base for different browsers - if that's not viable then it isn't viable - but the core question is: Is there any world in which you would consider moving to a different base?
