Firefox remove the API required to make this plugin work, it depends on XPCOM but it is not available anymore
for use with extensions. There is no API on WebExtensions available to provide this functionality.
The closest alternative to produce a high quality PDF file from web content is to create the file on server
side using puppeteer and send to print from there.
I think there is also a silent printing on the client using printjs but I didn't try it.
I hope that in the future Firefox can expose its printing API and make it possible to create a PDF file and produce silent printing again.
