What Spectre and Meltdown Mean for WebKit
I wonder if this shouldn't question whether we should still allow all websites to run javascript by default.There are websites that genuinely need to run some code, like webmails, online trading platforms, online games, etc. But 99% of the websites have no good reason to do so. Javascript is used to make up for the shortcomings of html/css (different rendering for different screen sizes, lack of local validation of forms, etc), for the mere convenience of developers and for user hostile activities (tracking, messing with default behavior of the mouse, keyboard, clipboard, scrolling, etc).This might be an opportunity for revisiting html and making it better. An ecommerce, a newspaper or a blog should have no reason to execute client side code to render. Once we have a good enough markup alternative, executing javascript can become an optional feature requiring user authorisation like accessing your camera or location.[edit] also at the very least it should lead us to question the chain of trust of javascript. When I visit abc.com I should only execute javascript from abc.com or a subdomain. No script either hosted on a non abc.com domain or appearing in an iframe should be executed.
