We've had lots of news about this coming for months, but with Mozilla's quite low market share, and the share of those users that use extensions - who's really caring about this other than some power users?
People b***h about Firefox's (lack of) market share, Mozilla doing stupid things (fair criticism), Firefox not having X (extension support on Mobile, moving from legacy extensions to standard manifest format)
Then people will still bring up this baggage even when something good happens, will refuse to move away from the browser monoculture/monopoly, s**t on Firefox devs
FFS, something good happened. No other browser has this. Yet people will find a way to lessen it. For what? What benefit?
