While Firefox alone doesn’t transport you to that internet, I think the point is that browsers like Firefox are one of the pieces that makes up that older experience. Fediverse being another, I would say a lot of us are here because we remember this style of social media.

They have improved the intentionality of the AI features, I wish they had it opt-out and easily configurable from the start. I moved to Zen a while back (which still relies on Firefox pushing out updates)
