You really can’t. If it was only HTML and CSS, any accessibility program would be able to select any part of the page, and easily alter the CSS and HTML. That is next to impossible now because of JavaScript.
It shouldn’t be up to the website developer. It should be up to the browser developer. You don’t blame a lemmy instance for poor accessibility with Jerboa.
Flash didn’t allow arbitrary code to run. It had a very limited scripting language (which design-wise is superior to JavaScript, by the way) to control canvas elements and playing sound. You couldn’t execute programs on your computer.
If by late you mean right before action script 2. I was making flash games back then and I remember it being unable to access virtually anything without first triggering a prompt, which you could disable by right clicking, and going into properties.
Yes, through NoScript. And it should be blocked, not blockable.
It is funny you mention evercookie because that was a JavaScript library, and affected all cookies, not just flash cookies.
Flash cookies being sharable between browsers was bad, but you could still easily clear those cookies, that is until a certain JavaScript library started restoring them automatically.
