It works. I use the whitelist mode for specific websites. The user interface throughout the extension could use some bells and whistles.

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.

Thanks to the author.

It's really useful!

it's doing what it's supposed to do

Very useful add

great experience

when your bank has stupid expectations of updates switch your agent. Else run a virtual machine

Great at bypassing browser discrimination

f you youtube

To anyone having an issue with cloud-flare looping verification box, go to user agent options>white list mode and add www.cloudflare.com. This fixed the issue for me and hopefully for you.
