In what way?
I switched recently to Librewolf, but as a long time Firefox user (of which Librewolf is a fork anyway) it didn’t seem unusable out of the box. There are some settings for privacy and studies etc you mght want to change, but they are all very obvious in the GUI preferences.
I did personally go into about:config to set a few things, like not allowing searches from the address bar because I’m weird, but what makes Firefox no good for the average user?
Yep. My Dad in his late 70s uses this system and it works great for him.
People make fun of it, but for people with low tech literacy this is actually far better than having a mish-mash of solutions where some their logins end up automatically saved in iOS on their phone, some are saved in Chrome on the desktop, some are just in their head, they don’t know where anything is, and are constantly losing access and resetting credentials all the time.
And it definitely reduces the burden on me of parental tech support, when its all in the book.
