Is there a way for one to use this on android FF?

Edit:
Found one. Bookmarking the following(got it from view-source:) worked:
javascript:(function(){var d=document,s=d.createElement('script');s.crossOrigin='anonymous';s.src='https://unpkg.com/@mourner/bullshit@1.3.0/bullshit.js';d.body.appendChild(s);}())
