Ad blocking has become a safety issue. My parents are at an age where they fall for things. If a malicious ad pops up and offers to install McAfee, some other form of crapware, or outright scamware, they'll click that ad and install the thing. Then I'll get called over when the computer starts acting screwy. If Google, MS, etc. had ever gotten together and developed a way to filter malicious ads out of their own ad services, maybe we wouldn't be having this conversation. They didn't do that and probably never will.

If my parents get a new machine, the first thing I do is uninstall or, at least, delete the icons for Edge, Chrome, etc.. On goes Firefox, uBlock Origin, and a couple other extensions. They don't care what browser they use. They can't even name it. I just try to make sure they use a browser that isn't horribly unsafe.

We should all do this for people we care about. Don't ask them what browser they prefer. Odds are they don't know or care. Don't try to convince them to install Firefox themselves. They won't. Just do it for them. Think of it like picking up a rusty nail that's on their lawn. Sooner or later they're going to step on that thing if you don't.
