Ao3 Savior not working with Firefox Quantum

Firefox just updated to Firefox Quantum on my laptop. I had to reinstall greasemonkey, and my ao3 savior script is still available, but it's no longer working on hiding the blacklisted works.
Is anyone else facing this issue? Is this a known issue which can be fixed?

Yes, 57 broke most things in Greasemonkey. Use this instead: https://addons.mozilla.org/en-US/firefox/addon/tampermonkey/

Thanks for replying quickly!
Is there a different ao3 savior script used for tampermonkey? Please give a link to it.
I've installed it and restarted, but the old script is showing errors.
Thanks again

Aaaand.. Just had to reinstall the script as well. It's working now.. Thanks for your help!!
