Hi, love the script. Is it possible for it to work on Pdf?

Unfortunately, it's not possible for add-ons to inject scripts into PDFs in Firefox's built-in PDF viewer. It might be possible to inject the script another way, but it wouldn't have access to your stored word sets. Hmm.

If you saved the PDF to your own computer first, you can open it in the web app version of the viewer here:

https://mozilla.github.io/pdf.js/web/viewer.html

(There's an Open File button to the left of the print icon.)

The script can run there, but it's pretty ugly...
