I don't know why there's so many people saying this doesn't work and I barely understand this thing, but I used this to make YouTube load faster. Spoofing as Chrome, the site loads in half the time than it would take without this extension. Unfortunately it does seem to break some captchas, like cloudflare, as in after pressing "I'm human" or whatever; it just loads and the the captcha gets refreshed, so it never proceeds to the site.
