Online pdf always come up as non-fillable

Question

Running Firefox 34.0.5. Whenever I click online on a pdf, it always loads as non-fillable (if it is a fillable form). There is a bar at the top to request 'Open with a different viewer'. Then I select to open with Adobe Acrobat 11 and I can fill in the form. Why this double work? In Windows explorer, all pdf forms are set to open with Adobe Acrobat 11. I do have an enable add-on for Adobe Acrobat in my Firefox. What am I missing? Thanks in advance for your help.

Answer 1

Firstly you will need to buy a Reader Extensions license (this allows Reader to save the form data - otherwise the client will require Acrobat).
Once this is done, you will then need a button (called "Lock Down" or something) that executes a script that makes all of the fields readOnly and updates a form variable (say, "locked") to indicate that the form is locked. You will also need to add a script to the initialize event that checks for the value of "locked", then executes the readOnly script (if the form needs to be locked down).
An example of a readOnly script can be found on page 434 of http://www.adobe.com/go/learn_lc_scriptingReference (see "Disabling all form fields" script)
