True, but what are the alternatives? Bloated Brave? Bare Chromium without a proper adblock (I mean unlock of course)? Firefox is still the best browser there is, even with these flaws.
Librewolf is not recommended, but rather just install Firefox and apply arkenfox to it. That's basically what Librewolf is, just with that and uBlock Origin pre-installed. But what you lose with Librewolf is them being behind in security updates, sometimes multiple days (!).
