194028 – Add limits to the amount of JavaScript that can be loaded by a website

Now this is a feature request I can get behind!

A user must provide permission to enable geolocation, or notifications, or camera access, so why not also require permission for megabytes of JavaScript that will block the main thread?

Without limits, there is no incentive for a JavaScript developer to keep their codebase small and dependencies minimal. It’s easy to add another framework, and that framework adds another framework, and the next thing you know you’re loading tens of megabytes of data just to display a couple hundred kilobytes of content.

I’m serious about this. It’s is an excellent proposal for WebKit, similar to the never-slow mode proposed by Alex for Chromium.
