How paranoid should one be of, say for example, a wasm vulnerability exploited on zero day by a bad JS ad?
I am scared for my parents to get exposed to this kind of thing from bad ad network actors. Does anyone have some practical concrete recommendations they took? Like I don't think they can install ublock origin and whitelist sites on demand in Firefox they way I do.
The only practical thing right now is to make sure they don't have the money on device and have 2 fac for email and bank accounts. But every now and then there are phishing attamepts that they could fall prey to.
Install uBlock Origin and don't whitelist any sites. The default filter lists break almost nothing, only once you start including the "annoyances" lists etc. do you start running into significant breakage.
Without an ad blocker, they will be exposed to such an amount of social engineering (ranging from dropshipping sites, to subscription scams, to scam shops that don't ship at all but steal your CC data, to fake sites for government services, to attempts to trick you into installing malware) that you can't expect them to resist it. If installing uBO seems hard, resisting this or cleaning up the consequences is harder.
The amount of "hey have you heard of this great new product I saw" <photo of a handwritten note of the content of a scam site> went down from weekly to near zero once I got a relative to use an ad blocking browser.

It's tough. One option is to hope/assume that exploits only compromise user accounts rather than the whole computer.
In that case you can blacklist the banking website from the day-to-day browser as a reminder to switch to the other account, and configure the other account's browser so that it can do little else.
