In Firefox, I don’t remember having something similar. That was like 5+ years ago, I believe profiles were there, but perhaps less easy to use.

The profiles feature in Firefox haa been there for a long, long time—more than a decade, and possibly longer than Chrome has existed—but not many people read the documentation to find the command-line switch to evoke the selector, and they've never been terribly easy to find from inside the GUI.

Well, it often feels like every "Linux security issue" flagged in the tech press is a privilege escalation, but I admit that I haven't sat down and done the math.

Exactly. It's Yet Another Privilege Escalation Vulnerability. Unless you're dealing with a multiuser machine, the attacker first needs to use some other vuln to get into an unprivileged account. Without that additional vulnerability, this exploit is useless.

We don't talk about 1997. It might hear. 😱
