The Firefox repo gets 100-300 changesets per day, up to 1000 commits per week. Around 100-150 contributors land those in any given week. That's activity comparable to Linux or Chromium. And, the release schedule is accelerating from a four-week cadence to a two-week cadence this fall.
Just because other efforts and initiatives are flasher or noisier doesn't mean Firefox isn't the main priority.
