Very minimalist, follows trendy designs almost to a point where it's a pain in the ass to use. Are there no options to speak of? What happened to blacklist?
This started it all but it hasn't kept up with other add-ons.
Since the release of WebExtension version Greasemonkey became significantly slower when dealing with heavier scripts. If core functionality is getting there (though really slowly) performance is terrible comparing to non web-ext version or Violentmonkey.
FF 56 Greasemonkey 4.1 - pure junk. The Greasemonkey category is gone from add-ons page which means no easy way to order and maintain a large group of scripts. Use version 3.17.
