Startpage Privacy Protection is obviously based on EFF's Privacy Badger and does an okay job, although it's not as mighty as uBlock Origin, for example.
Though, what I find irritating is that the addon apparently injects additional HTML elements into all websites for unknown reason. Edit: As Startpage said, that's for Escape Route or hiding their own promotional messages on startpage.com, which is fine.
Thanks for trying our extension! Any HTML you might see is only used for one of two purposes: either to enable the Escape Route feature (Click Esc three times to blur the screen and four times to exit the page you’re on) or for Startpage to determine whether to show or hide promotional messaging about the extension on our homepage. No tracking whatsoever!
