Greasy Fork镜像

I modified the script a lot:

• Removes the big obvious button, replaces the ![community] links instead
  • on mouseenter to get around the elements getting reset by something after loading
• It works even if the url shown by the browser hasn't changed yet (weird)
• I've only tested it on Firefox
• Use it if you want.
