It's easy to intercept page loads
While looking for a way to make an addon for better web experience, I found these articles:
https://developer.mozilla.org/en-US/Add-ons/Overlay_Extensions/XUL_School/Intercepting_Page_Loads
https://developer.chrome.com/extensions/content_scripts.html#run_at
http://developer.chrome.com/extensions/webRequest.html
So, I can stop the page from loading even before it actually makes any HTTP request. For example, instead of Yandex front page (213,8 KiB) I can show prepared input field, which loads in approx. 0 seconds, and takes 0 bytes of traffic. These're the good news, aren't they?
