I think FF is in a difficult place.

The only community they have any penetration in is the developer one (in its prime non-technical people would tell me they used Firefox since IE was insecure. Their techy friends would tell them to use it and the message carried some actual weight back then).

Today they are a large organization that needs to make money to sustain itself, while facing declining usage, and less favorable terms for search engine integrations.

And our community (developers) is the least likely to take kindly to the increasing monetization slop (promoted articles, pestering about pocket and their VPN offering, continually requiring accepting new ToS, reminders to use new features, etc).

I mostly use FF, because I think we'll lose something if it disappears (for example, DRM will become intolerable, web inspectors will become more opaque, and generally future web standards may be much more controlled by a small set of large orgs with their own interests).

But I use FF with less enthusiasm every passing day
