Note: this is a question about Google Drive, not Firefox options.
I've been using Google Drive and Docs a lot, so I tend to keep .PDFs on Drive as well just for convenient storage.
But I don't like reading .PDFs using Google's viewer. I'd prefer Adobe Acrobat.
I have Firefox set to use the Adobe Acrobat plugin, which works fine for browsing the internet. But when I open a .PDF which I've previously saved to Google Drive, the browser uses Google Docs' viewer, even though I'm not converting the .PDFs to Docs' format when I download them.
I've tried to find a Drive-compatible Google Apps version of Acrobat but there doesn't seem to be one. And the "File" menu "Open With" in Google Viewer gives me only one option (Google Docs).
Anyone know the answer? Thanks.
