WTF you on about? Firefox has the NoScript extension, which Mozilla recommends?

Good on chrome I guess but if they are testing blocking js then I assume they are about to offer a less easy to block alternative

dramatic irony

Yep, noscript on firefox has been available for like 15 years. And it certainly does "break" some sites as it blocks scripts by default. It can be a pain, though I consider it the safest way

Since the web works via a DOM (Document Object Model) and a document that needs to execute active content to display anything is not a document, a webpage that needs JS to load the document can safely be considered broken.

About 1/4 is broken, about 3/4 of the working ones show no popups/"paywalls" anymore.

I was trying to explain it more practically, but yes the web is a wasteland.

You are talking about the difference between a website and a web application. Nothing is broken. Given that the alternative used the be Flash/Coldfusion I’m not sure this way is worse.

I like uBlock Origin's "medium mode." It's a nice middle ground

But does not install by default.

Also while you can chrome has JavaScript permissions page, Firefox doesn't. Which means you can't control it.

Matter of fact there was a long period of time before where Firefox browser would reenable the about:config JavaScript preference when you switch it off.
