I already use container tabs for my dev. (Usually have to test an app using multiple test accounts). I have not figured out how to run a second copy of Firefox that is fixed into a different workspace -- but if I ever do, I will switch on my work laptop. My personal laptop, an old 2011 Mac Air is definitely switching. Chrome just runs too poorly on that now, and container tabs is too useful. It's really interesting, feel like coming to full circle. 10 years ago, I switched to Chrome because of the multi-process isolation -- Firefox leaks pretty badly then.
