I can no longer open .pdf files in Firefox 4
Ever since I moved to the beta version of Firefox 4, I have lost the ability to view .pdf files in Firefox. I was convinced this was a problem totally with Firefox, but at around the same time I upgraded from an old G4 PPC laptop to a new Macbook Pro. Now I find I can't view .pdf files in Safari either. Is this a problem with Firefox, or a problem with the way I have configured my new computer?

I started having the same problem when I downloaded Firefox 4 beta and continue to have the same problem with the non-beta version. However, the pdf links work fine in Safari for windows and IE, so the problem must be with Firefox. I'm about to go back to an older version.
I did have an issue with a PDF at one point, but it only seemed to be on one site, so I promptly forgot about it (and put it down to a bad file) - anyone got a site link of a broken PDF situation I can point my browser at to test?
Opening PDF-Files is a function usually provided by a seperate application (like Adobe Acrobat) through a plug-in. Have you tried to reinstall you current PDF-Application? When you click Firefox (upper left corner) -> Add-ons and click on "Plugins" on the left side, do you see your PDF-application displayed there (e.g. Adobe Acrobat)?

When I went Firefox 4 beta, the plug-in I was using was not compatible. I recently found a compatible plug-in; unfortunately it runs in 32-bit, and my 1Password plug-in only runs in 64-bit, so I have to choose until a compatible 64-bit PDF viewer plug-in becomes available. Thanks for the advice!
I managed to get the Adobe Reader plugin working by following the instructions found on the PluginDoc link, which can be found at the bottom of the Plugins page.
We are no stupids, pdf viewer is a plug-in of Firefox, (Firefox pdf plugin), but in FF4 it doesn't work. However, it's incredible that Firefox doesn't include a pdf viewer by default. You don't need to save every pdf that you want to see in the web.
I have the same problem and I agree with firebunny. This is really bad style from Mozilla. You should have thought about a problem such as viewing pdf's in the browser and compatible pdf-reader plug-ins.
My Adobe Acrobat plug-in was disabled by default when I installed FF 4 rendering viewing and downloading pdf's impossible. Now I am stuck with this browser and am considering going back to the last 3.6.16 version that I still use at my workplace without any problem.
Also I agree that this has nothing to do with the pdf readers that should be installed on the PC but with FF 4. I can prove this since I installed foxit-reader which also comes with a FF compatible plug-in. Neither here did selecting this as the default pdf application help nor does it enable downloads.
I too had the same problem, however the solution turned out to be real simple. Simply first close Firefox, then re-install the most current version of Adobe Reader (Vers. 10.0.1), and re-open FF. All is working well for me in that department
Finally I manage to solve the problem. The instructions on [page] helped me, but they are not up to date.
- You have to find nppdf32.dll in your adobe acrobat folder.
- Then copy the file to C:\Program Files\Mozilla Firefox\plugins.
- Problem: the folder doesn't exist in the new Firefox.
- Solution: create the folder.
- Everything should work after a restart of Firefox.
I just don't understand why there is no longer this \plugins folder and why the plugins are scattered everywhere.

Screw this! Went back to FF 3.6.16 and viewing and downloading pdf's now works like a charm again. That goes for Adobe Acrobat as well as Foxit Reader.
When you have finished testing your FF 4 beta let me know and I'll move on to it once all the flaws and errors are corrected.
Disabling PDF Download fixed it for me.
This is a shame because I really liked PDF Download, I hope there is an update soon.
RE: plophy's suggestion of copying the dll file to the FF folder...
This worked for me! However the plugins folder was already there in the Firefox folder. All I had to do was copy the dll file to the plugins folder and restart FF. Worked like a charm. THANK YOU!!!

I went into options in FF and changed the default pdf reader from Adobe Acrobat to Adobe Reader since it now costs for Acrobat, I think. Anyway I don't have Acrobat. The files download but at least I can read them now.
If you have the PDF Download Add-on you must disable it. There appears to be a conflict with Acrobat. Also in Tools-Options-Applications assign Adobe Acrobat Documents to "Use Adobe Reader". You must do this if you want to save the file as a PDF. For some reason (?) if you use the "Use Adobe Acrobat" selection, Firefox saves the document as an htm page. Go figure?
That hasn't been an issue. I have had Firefox set to open .pdf files in Acrobat and it works fine. I just prefer to read them directly in Firefox rather than having to flip back and forth from one app to another. I am able to safe .pdf files as .pdf files just fine in Acrobat.
I have the nppdf32.dll file in C:\Program Files\Mozilla Firefox\plugins, but I still can't view PDFs.
Hi Uninstall acrobat reader 10 and install acrobat reader X Worked for me.
Hi Does any body file a defect for this issue? If Yes, Please post your reply.

To resolve the problem, i uninstall the module PDF Download and install the module gPDF.
