There are many kinds of vulnerabilities. Most are pretty mundane afaict. Breaking sandboxes and reading out your entire RAM is basically game over, existential vulnerability (second only to arbitrary code execution, though it can give you SSH keys I guess).

The mitigating factor is actually that you don't go to malicious websites all the time, hopefully. But it happens, including with injected code on ads and stuff that may enabled by secondary vulnerabilities.
