It requires literacy to know that that’s an option and to know why it’s a good idea.

I’ve met plenty of tech illiterate but otherwise smart people who just use edge, or a mobile phone and whatever browser it has as a default.

GP mentioned a couple of user filters. If that's not technological literacy I have an SAP migration to sell you.

You need to be savvy enough to know how to deal with the inevitable "broken" site you run across (ideally by leaving and never returning, but sometimes that isn't an option).

Try asking random people on NYC street if they have heard of Firefox and uBlock Origin.

A large portion of users (a majority, imo) think "web browser" is a specific app they open, rather than a type of app, and don't even understand that there are multiple different ones to choose from.
