Firefox 11.0 Installed Acrobat plugin 10.1.3 today doesn't work (ok in Safari) Installed extension PDF viewer 0.2.537 can now view PDF in firefox

This is for information purposes. I installed Acrobat plug in today 10.1.3 and I get a blank tab when trying to open a pdf document in Firefox 11.0. This plug in works in Safari. I disabled the plug in in Firefox and installed the extension PDF viewer 0.2.537 form Mozilla and documents open fine. Just wanted to let someone know1.3

If you want to use Adobe Acrobat, you can just change the preference that was messed up:

Go into Firefox > Preferences > Applications and look for "PDF file"

Next to that, select use Adobe Acrobat (or use Preview) rather than Adobe Acrobat NPAPI 10.1.3

Adobe's NPAPI plugin doesn't work in 64-bit Firefox ... there's probably a bug where the Adobe Reader update is setting that preference.

Great! Glad that the PDF add-on (I assume pdf.js) is working well for you.

I don't have a "PDF file" but rather an "Adobe Acrobat PDF Document" entry in my Application Preferences. When I change that entry (and the other two "Adobe Acrobat ..." entries) to "Use Adobe Reader (default)" from the NPAPI 10.1.3 plugin, I get the same behavior (yes, I restarted Firefox). A window pops up when I attempt to view a PDF document, but Adobe Reader never comes up and I never see my document.

Any idea why? Everything worked fine with the previous (10.x) version of Firefox.

Are you sure you have the same problem? This is specific for OSX users who recently updated Adobe Acrobat (and possibly Reader) and was caused by this update. If you have a different problem, can you please start a new post so that it's clear?

Well, the symptoms are the same. I'm running Mac OSX 10.7.3, Firefox 11.0 (recently upgraded and haven't been able to view PDF documents since the upgrade), and prior to my changing the setting for the "Adobe Acrobat PDF Document" file type, had been using the "Adobe Acrobat NPAPI 10.1.3" plugin to handle this file type.

In any case, I still can't view PDF documents in Firefox (but everything works fine on the same machine using Chrome).

Oh, forgot to mention, I did just recently update Acrobat Reader too -- so it might have been the update of Reader, rather than the update of Firefox, that broke PDF files. I didn't pay much attention as to exactly when PDF files stopped being able to be rendered in Firefox.

Cww, Very helpful thank you!

For those who haven't a clue about these things (like me), I followed Cww's instruction but instead of finding "PDF File", I found ADOBE PDF DOCUMENT and I selected USE ADOBE READER (DEFAULT).

It worked!

Problem solved!

I did what Lili2012 suggested, as Cww instructed....Although with a little bit of a twist...

I clicked on Firefox, clicked Preferences, clicked Preview Document (application/pdf), choose Use Adobe Reader (default)

That solved this mystery
