Firefox 11 not displaying pdfs with Adobe Reader update (MacOS)

Since updating to Adobe Reader 10.1.3, I noticed Firefox 11 does not display PDF files. It just shows a blank screen.

The only workaround I found is disabling the Adobe Acrobat NPAPI Plug-in (ver. 10.1.3) the update installs. Firefox will prompt which application to use.Choosing Preview allows the PDFs to display correctly.

Neither Chrome or Safari exhibit this behavior, nor does Firefox 11 (Windows) with the update installed.

Has anyone else experienced this?

I've found another workaround to this problem. If you open Firefox 11 in 32-bit mode, it will be able to display PDF files.

To open Firefox in 32-bit mode, quit Firefox, go to the Applications folder, right-click on Firefox and click on "Get Info".

Then, under General, you should see a checkbox where you can have Firefox open in 32-bit. Close this window and restart Firefox and you should be good to go.

Thanks for the work around! Anybody know of other updates to fix this problem without having to run Firefox in 32 bit mode?

This is a re-post of a success I had fixing the same problem. Go to [Menu] Tools/Add-Ons/Plugins and disable the Adobe Acrobat NPAPI 10.1.3 reader plugin. It seems to be a common problem, and Adobe will fix it. But for now, this may work.

With this plugin disabled you'll see your download dialog box again.

Thanks for posting the workaround. But damn, now none of our PDFs will display for people running FF 11 and Reader 10.1.3? I really hope they fix this bug soon.

This issue appears only using the combination MacOS X, Firefox 11 with the Adobe Acrobat (Update 10.1.3) Viewer Plugin. As workarround you could do a "rightklick" and "save" as the pdf will work with the Acrobat viewer itself

From: https://support.mozilla.org/en-US/que.../925239.

You can also 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.

This is incredibly frustrating. I have FF 11 with Adobe Reader 10.1.3 on the latest MacBook Pro 17", just bought. With the pace of work I have, and the constant use of internet sites that require me to glance at, review, skim PDF documents in another window, I have to have this capability. I DO NOT want to downloand the PDF clutter and create more work having to clean the stuff out. Safari has its problems, but the PDF viewer works there. However, Chrome will be my home browser now. FF used to be so reliable, and compatible with everything! Bye Bye For Now. (BBFN?)

chemenway,

I understand your frustration. My organization posts bids and RFPs to vendors using PDFs, and a lot of these folks use FF11/Reader 10.1.3. We basically now have to edit all those posts to alert them to this problem and offer a workaround.
