~~Hot take and I can guarantee this will be downvoted but I think people are putting way too much blind trust into Mozilla for this.~~ (edit: Apparently not here, pleasantly surprised at that)

They just purchased an advertising company, they made the T&C waive your right to a class action lawsuit. They keep giving their CEO raises and laying off their workers. Mozilla is actively enshittifying but people don't react until it's too late because it's a boiling frog situation.

Whether you think the feature is useful or not, Firefox is unfortunately shifting away from being a privacy-focused user-focused browser. The saving grace is that it is open source and forks can be made of it, "Firefox" itself can survive anything as long as there's enough interest to keep it alive.

I think that Mozilla does great work, but they've lost sight of their goals, and are changing focus. This is not necessarily a bad thing, but this needs to be looked at objectively instead of with brand-loyalty. At the end of the day, they're just another company with financial interests prioritized over user interests.
