I’ve used Librewolf until pretty recently and I say it’s not for everyone. It’s hardened Firefox made into its own thing for people who want the benefits of hardened Firefox but don’t want to go through the effort of hardening their Firefox install.
There are some sites that wouldn’t work in the strictest settings. As far as I remember, the most problematic sites with Librewolf are those that demand way too much in terms of privacy and security, so I took it as a given that if a site doesn’t work with Librewolf (with me using the default settings), it’s not worth it to enter to begin with.
If the earliest sports were a way to practice skills needed for hunting or warfare, then making an e-sport out of spreadsheets is going back to the roots of sports. It’s practicing skills needed for your daily job.
