Pure curiosity, what's the advantage of this? What am I missing?

The user can't leave the malicious domain, but they also can't interact with the page, because the dialog is in the way. And even if they could, are they really more likely to trust the site after it's made a bunch of random popups appear in a row?

Is it just malice? What does the malicious site gain?

Yet another reason to use an extension like uMatrix to disallow javascript by default, and only allow the absolute minimum that sites you trust need to function.

I don't believe this requires javascript to work.

I assume the idea is that on the page visible behind the dialog are instructions to call some number, or open the download, or approve the extension the site wants to install.

Not allowing JavaScript turns into a chore when you find out that websites break in non obvious ways. I do not want to manually enable/disable JavaScript when the browser is a means to an end for me.

I consider dealing with the consequences of hacked-in accounts or a hacked-in laptop to be the bigger chore.

I say it every time that people say "Firefox is great now!". Just look at the Bugzilla, and tell me that among the thousands of reports (many of which have gone untriaged for around a decade!) there aren't at least a handful of serious issues like this.

One, among many, of the reasons I use Chromium is that I see reports taken absolutely seriously, especially any report with any potential security outcome. Even seemingly minor issues or feature requests I've filed with Chromium get thoughtful and prompt responses.

I wish Mozilla the best, but the quality of Firefox is low in a way that I notice every time I use it; I'd appreciate it if they go back to basics and actually try to address at least the known issues with the software.

I've used a few solutions: privoxy, noscript, uMatrix and now uBlock origin. The later was a little confusing when I started using it, but now I get it and love it.

A very good thing is that most websites use external javascript to implement the most annoying "features" like asking for consent, tracking, autoplay and diverse pop-up junk.

Also it includes the "cosmetic filtering" that allows me to block html elements by name, very useful for subscription requests.

Only when I browse in other people's computer, I'm reminded how screwed the web really is.

Having spent a couple of years working for tech support for a large retail chain, I can confirm that this happens much more often than you might think. Non-technical users are floored the browser locking up, especially if the site starts to do something alarming like play an audio file telling them their computer is infected. If they were lucky and brought it to me in that state, I'd teach them about their task manager and how to close the browser, and warn them about visiting suspicious sites. But if they actually called the number, and in some cases, allowed the scammers to remote into the machine... all bets were off. There was no telling what we would find.
