Hi! I just updated it, but GreasyFork isn't accepting the new code. Right now, you can update directly from either the GitHub or from OpenUserJS sites, but you'll need to wait a bit before GreasyFork gets updated. Sorry for the inconvience.

Please, update this script.
It doesn't work anymore since the last forced github redesign.
