TY!

Awesome. But when this addon is active, I cannot view or download a file from Google Drive.

Absolutely perfect!.... It save the day....

I don't know why Firefox otherwise insists on saving the file instead of just displaying it. This plug-in did a great job of seamlessly resolving that, whether I open the PDF from within Firefox, or I open it by double-clicking the file on my desktop. Works great!

Absolutely perfect! Well done Merten! Keep up the good work
