For my sins, I interact a lot with PDF files generated by the South African Revenue Services. Anyone else who uses these will be able to tell you that even the most static of their documents and forms will not open in any form of pdf reader other than Adobe v 9 + (Please correct me if I am wrong!)
Anyway, so mostly, I am dealing with forms that have to be filled in and then submitted. The submission is only possible if the form is accessed within a browser. Opening it in Adobe Reader itself one is able to fill it in, but the submission process fails. Hence, I *must* be able to open pdf documens directly in my browser.
Which leads to where I am struggling. I have Firefox (17.0), Chromium (22.0.1229.94) and Google Chrome (240.1312.56). installed on my LMDE 64-bit installation. I have acroread (9.5.3-dmo2) installed.
In firefox, under preferences for handling pdf files, the only available options are "Always Ask" or "Use Document Viewer". I have a link to /opt/Adobe/Reader9/Browser/intellinux/nppdf.so in the /usr/lib/mozilla/plugins folder. about:plugins lists all my other plugins that are in that folder, but does not list the Adobe Reader plugin.
I've created a link to that same nppdf.so in /opt/google/chrome/plugins (the same place I made the java plugin link - which does work). chrome:plugins does not list the Adobe Reader plugin and attempting to open a pdf only allows it to open in Adobe Reader outside of Chrome (incidentally, is there a setting in Chrome somewhere to determine whether it should open inside the browser or not)?
I haven't really explored trying to get it to work with chromium.
If anyone can give some guidance I'd be greatly appreciative.
