I regret to say I no longer trust Mozilla in this specific sort of case. As an occasional-but-regular filer of bugs and user of Nightly for my daily driver for over ten of the last twelve years, the feeling I have is that where a decade ago they generally wouldn’t ship a thing until it was done, increasingly often in the last few years they
have been shipping things despite known significant problems, only finishing things months later, but leaving users in the lurch in the mean time.
(Most recent example that I have in mind: they switched content dark mode from matching OS theme to matching browser theme in 95, despite quite a few immediate and detailed objections as soon as the patch landed on Nightly—and yes, I’m willing to admit that the change will match what some, perhaps more, users want—but didn’t expose it in about:preferences until 100; to my eye, they should fairly obviously have reverted the change until they had that setting, or at the very least mentioned the about:config pref to restore the old behaviour in the release notes. At least in that case there was still a pref for it.)
