I was thinking the same thing. I'm pretty sure Librewolf already got this covered, and even it doesn't, it can still be easily done.

Librewolf isn't a mainstream browsers, and it breaks a ton of stuff.

How do you balance using Librewolf default cookie blocking with high frequency sites like email/social media/bank accounts? I find there's a convenience with being logged into some of these sites like the Brave article discusses, instead of having to log in from scratch multiple times a day

Or do you never enable cookies? Just curious
