Librewolf was a candidate I would have installed and tried, but its missing a feature: it does not have builtin support for passwords.

I always disable password management by Firefox, but I noped out of LibreWolf because it doesn’t allow users to block all cookies and then whitelist domains for cookies.

I suspect what a lot of people want is a custom version of Firefox with the garbage surgically removed before compile; where the opt-in options still exist for:

• browser-kept passwords,
• browser-kept payment details,
• blocking cookies,
• whitelisting cookie domains,
• crash reports,
• remote changes between updates,
• scanning everything you download for danger,
• scanning every site you go to for danger,
• etc. .
