Love this extension, as it saves so much time (particularly the simple print mode) but currently neither button are showing, even with a fresh install of firefox and the extension. Hopefully it's just a bug that gets fixed in an update!

Works to print multiple threads. O could only make it work for the "simple printing" option through. Which was enough for me.

Genial!! muy recomendable

I needed to PDF a multitude of emails as required by the government when I was going through Unemployment Assistance in Canada. I happened upon this add-on and could not have been more lucky.

Saving emails to PDF was immensely easy, quick, and hassle-free. I had already decided to review this add-on afterwards but made myself do a proper write-up once I discovered no one else had.

TLDR; Use this if you need to PDF emails. It's free, easy, and DOESN'T require a sign-up or subscription. ❤
