I can't open PDF documents

When I click on a PDF file, a new tab opens. It gives me the opportunity to open the document directly or save it - that's what I have set preferences to do. When I try one of these options, however, nothing happens. It doesn't open a new empty tab. My specs are lower. I have run all relevant software updates.

System: OS X 10.8.2

Adobe Reader: 10.1.5

Firefox: 18.0.1

I've seen this problem on other posts and I did some research on the web. I tried the solutions that were provided and worked for other people, however I have noticed they were running old versions of some software, etc. Interestingly, I CAN open PDFs that come to me or that I send through Gmail.

I did the following in accordance with the notice that I saw:

Erased my downloads list

Tried to disable the NPAPI Adobe plug-in

In my Firefox preferences: I put open Adobe PDF documents. I also tried with preview. None of them worked.

I appreciate any help you can offer.

That worked very well for me.
In the case your application preferences file is corrupted, you could try rename or delete.
Help > troubleshooting information > 'display the folder '.
The file is named mimeTypes.rdf and if you rename or delete, there must be regenerated with a default the next time you restart Firefox.

  • I can't open pdf documents after installing the XI player

    Hi I just installed Adobe Reader Xl. I can't now open a PDF - the screen is blank and closes after about 10 seconds. When you use the advocatus it indicates there is a problem of compatibility. I have re-installed, I looked at my options settings internet but still can't solve the problem. Do you have any suggestions? I am running Windows 7 and Norton 360 first Edition software.  Doug cordially

    What is your version of reader?  Try to update to 11.0.4.  If this does not help, try...

    • Using Windows Explorer navigate to C:\Program Files (x 86) \Adobe\Reader 11.0\Reader, and then double-click Eula.exe and accept the license agreement
    • You can open Adobe Reader by itself?  If so, try to disable the Protected Mode [Edit |] Preferences | (Improved) security].
    • If Reader opens in itself, try to disable the Safe_mode in the registry; Download, unzip, then run the attached registry script
    • It might even be a malware problem; See http://helpx.adobe.com/acrobat/kb/reader-core-dll-error.html
  • Cannot open PDF documents/files

    I can't open PDF documents.  Had been able to before.  I'm using the latest Mac OS.  Now, have also downloaded the latest Adobe Reader.  Always without success.

    Well, the file is now empty. It has always been empty on your computer, or something is empty. It is a serious problem, but at least you know that Adobe Reader is not the problem.

    Is - this by chance something that save you when you look at them in Safari? If so, this is how save you. Do not use the menus. Do not use the toolbar of Safari. Use only the Adobe Reader toolbar.

  • Dell 2335dn Scan Manager opening PDF Documents

    We just bought a 2335dn to scan of files in a folder on our server, it works fine (except for the horrible menu interface). We have a problem that after each scan it opens the scanned document on the server that we don't want. We want other people on the network to have access to move/rename the created PDF documents. I checked the Scan Manager software and I can't find any option to do not open the scanned documents. Does anyone have any ideas?

    Nevermind my post.

    After looking at the Scan Manager I found under the directory you place in, (location) recording if you click on the Browse button and open the page of the dialog box you will find on the bottom a box to tick you can either open the document after (I think that by default) or not.

    Uncheck the open document after scanning, you should be good!

  • How to open PDF documents in the same window?

    Prof. Acrobat X / Windows:

    How to manage open PDF documents in the same window?

    When I open more than a single PDF docs and a second, third,... window opens, each document is opened in a separate window.

    In previous versions (Acrobat 8 Prof.), all the documents were opened in the same window.

    This is especially useful, because the windows are not spread over the entire desktop, and with ALT + TAB I can change between the documents, if I don't have that one window.

    Thanks for any help.

    This feature has been removed.

  • I can't open pdf files in firefox, and I tried all the solutions proposed by others. How can I reactivate pdf in firefox?

    I have recently switched to Firefox to Google Chrome, and I find that I can't open all PDFs from the web in some way in Firefox. I can't download them and open them in Adobe Reader and I can't preview them in Firefox, or I can use the plugin from Adobe. I tried to use the solutions posed by users on this site, but none of them have worked. Whenever I have an amendment to the settings to try to resolve this problem, change never allows me to view the pdf file, and the setting reverts to the previous setting after the browser is restarted. I don't like how to display the file, but I need to be be able to see a preview or I need to be able to download it.

    I use an adobe download add-on,, and I have disabled. Now, I can actually open pdf files in my browser shows a preview, or download them as I see fit. Thank you!

    But clearly, there is an error with the add-on.

  • FixIt can not open PDF files

    I can't open PDFs in Firefox - I get a gray screen stating "this plugin is vulnerable and needs to be updated". I go to updates for Fixit and the link takes me to things that I don't understand. I've been using Foxit Reader and this is my default player. I have no problem with Internet Explorer it works very well, it's just with Firefox which I prefer by far apart from this problem.
    I changed FixIt as my AVG Free software was telling me there is a problem with Adobe Reader XI (11.0.01) and so I got feed with it I deleted Adobe from my computer
    I had several suggestions to support Foxit, but nothing seems to work.
    I have reset Firefox by default given parameters always get the same message.
    Help, please

    Hi - Thanks for that - I just did a reinstall of Fixit as you mentioned, and the problem is always the same.
    I want to emphasize that I had five support proposals Fixit (yours being a) that I made and still the same problem. They're still trying to get out.
    I checked the internet and it seems I'm not the only one, but nobody seems to have the answer. Which makes me wonder if it could be a setting on the computer. But then why is there a problem with IE.

    What I pay a subscription for?

    Hi phillipk70320833,

    I checked your account details for the same ID you use here on the forums.

    You bought subscription Adobe PDF package that is why you are unable to open a PDF file.

    You should perhaps install Adobe Reader (free software) or buy a subscription to open a PDF Acrobat DC file.

    Let me know what you want so that I can offer others.

    Kind regards
