- by grahamperrin, 4 years agoRated 5 out of 5As a default, I prefer the viewer that's integral to Firefox … but that's a comment on Google's product.
(Google's 'Open original' button bears an upload icon, which is counter-intuitive; and so on.)
Opting to open the original allows the PDF to be viewed in Firefox.
I can't fault this extension. If ever I want Google's viewer by default, I'll simply enable the extension.
