In addition to completely disabling AI, I found the following setting extremely convinent to disable in about:config. They clutter up my right-click on a link or on text selection.

  browser.translations.select.enable
  dom.text_fragments.enabled
  privacy.query_stripping.strip_on_share.enabled
  devtools.accessibility.enabled

Now if only I could get rid of "Print selection" and "Services" when right-clicking, too (on MacOS)

Try modifying a webpage’s source to open with <html mozdisallowselectionprint>. If that works, you can make that universal using any page-mod plugin (though not necessarily the userstyle CSS-only ones). I’m mobile-only tonight so I can’t test myself, but derived from:

I wish we could also disable "Send via email" when right clicking a picture, I constantly misclick and userChrome.css does not work for the context menu on macOS since it's natively rendered...

		> userChrome.css does not work for the context menu on macOS Putting: #context-sendimage { display:none!important; } in that file works for me.

print.enabled should disable all the print stuff.
