As the name says, this script removes the annoying login requests from Instagram, Facebook, YouTube (mobile only, for the desktop version, try Youtube - dismiss sign in
), Reddit and Twitter. It might even show the search bar in Instagram mobile, if you are lucky enough (i.e. Instagram shows every time a slightly different interface and sometimes it's very easy to add the search bar even on the mobile version of the site).
Compatible with other Instagram scripts such as View Instagram stories highlights without login
and Instagram: Download Photo & Video
