• Once I updated to Firefox 11, I can't open the pdf files. It's more the computer, snow leopard and lion and more than one Web site.

  I've updated to Firefox 11 and now I can't open the PDFs Online. This has happened on more than 1 computer, using the two OS 10.6.8 and OS 7.0 and on more than one Web site. I tried to uncheck "block pop-up windows" in preferences, but which did not help.
  When I use Safari to open the same file to pdf, they open fine. Everything worked fine with my Firefox until I did the upgrade.

  I prefer to continue to use Firefox, but I can't understand the root of the problem.

  Has anyone else had this happen as well?

  Thank you, gentlemen, to find a "solution" to this particular behavior of Firefox. It is really curious that even if the screen is blank, you can indeed save the .pdf Ghost and then open the saved file to view. What is amazing to me is that this issue does not seem to be what makes the hit parade of the problems currently experienced Mozilla. Not everyone will be willing to do a research project extended rather than leave the ship for Safari, etc..

• Need to update my Acrobat 9.0.0 Pro to 9.5.5 version. Where can I find the necessary files - because the update does not seem to react (not supported any more, I guess that)

  Need to update my Acrobat 9.0.0 Pro to 9.5.5 version. Where can I find the necessary files - because the update does not seem to react (not taken care no more, I assume that). I wouldn't be forced to buy a newer software in this way...

  You can get all updates from here: ftp://ftp.adobe.com/pub/adobe/acrobat/

  Remember that you must install in order, one after the other.

• I can't open the PDF with Adobe Reader XI... get an error that "Adobe has stopped working" then it closes.  Any suggestions?

  I can't open the PDF with Adobe Reader XI... get an error that "Adobe has stopped working" then it closes.  Is it a question of Adobe, Microsoft problem or security issue?

  Since you talk about Microsoft, I guess you're on Windows.

  Can you open Reader by itself?  If so, try to disable the Protected Mode [Edit |] Preferences | (Improved) security].

• I can longer open attached pdf files. I am able to preview the files, but they are too small for me to read.

  * Original title: attachments

  Help, please.

  I did something wrong (AGAIN!)

  I had no problem with access to attachments to my e-mails, but a problem occurred just.

  I can longer open attached pdf files.  I am able to preview the files, but they are too small for me to read.  When I click to open all the I get now is a kind of icon (in Microsoft Office Picture Manager) with which I can't do anything.

  It seems I should have arranged for Picture Manager automatically opens attachments to emails, but when this happens, I'm stuck as what I try, I can't do pdf files appear as they did.

  The help file does not really help.

  I hope it is something simple, even an old fool like me can do with your expert (and, I hope. friendly) help.

  My fingers are crossed.

  My apologies if I offended Protocol - this is my first venture.regards

  Create a file association.

  1. download and save the attachment to the office.
  2. right click on the saved file.
  3. Select: Open with on the shortcut menu.
  4. click on: choose [default] program.
  5. Select: (Whatever you have installed a PDF reader).
  6. check: always use the selected program to open this type of file.
  7. click on OK.

  This should allow you to open these attachments directly from email address now.

• I have an annual subscription to Adobe export in PDF, but my computer died and I am setting up a new computer. I also need to download Adobe Reader or Acrobat to download and open the PDF files?

  I export to PDF, but can't seem to download and open the PDF files. I need to download something?

  Hi Lisa,

  To download PDF files, you have nothing else except a web browser.
  However, to open the pdf file that is downloaded, you certainly need to download Acrobat Reader: Adobe - Adobe Acrobat Reader DC Distribution

  Kind regards

• Acrobat Reader DC works fine and opens a PDF file without problem - until I have a word document open as well-, then the PDF file crashes. I can't open a PDF file, a word document is also open.

  For troubleshooting, you can disable the Protected Mode (https://helpx.adobe.com/reader/using/protected-mode-windows.html#id_94783) and see if that solves the problem. If the problem persists, please re-enable the Protected Mode to improve safety.

  Let us know how it goes.

• Update Firefox, now I get an error when you try to open the .mkv files, but not other video files

  I created an html page of cinema at home with links to movies on my hard drive. I have two types of links or href = 'file:///C:/Media/movies/Looney Tunes/MainMovie/Vol 1 Disc 3/VIDEO_TS/VIDEO_TS. IFO' for normal DVD or href = "file:///C:/Media/movies/Blu-ray/Lorax/mkv/THE_LORAX/THE_LORAX.Title800.mkv" for blu - ray. Both have worked fine (click on the link and the movie starts to play with Media Player Home Cinema) for a few years until what I recently upgraded to firefox. The .ifo files still open as usual, but now blu - ray links take me to a gray page that says "Video cannot be read because the daughter is corrupt" with a large "X" over it. If I open the html page in Internet Explorer and click on the link, it works very well (blu - ray opens by using Media Player Home Cinema). Also, if I directly open the .mkv files, they play very well (open using MPHC). Thanks for any help!

  Change your links to include the attribute type with the value of video/x-matroska . Example:

  <a type="video/x-matroska" href="file:///C:/My%20Videos/Cooking/Making%20Gingerbread.mkv">How to make gingerbread</a>

• I downloaded Acrobat Reader on my mac but when I click on the PDF file, it says that I him have not downloaded?

  I downloaded Adobe Acrobat Reader DC, by following the steps described on the Adobe site, several times, but when I click on the PDF in my Outlook emails - it says that I don't him have not downloaded?

  OK, what you need to do is to save the PDF file to your desktop. The PDF that you see with the message, even if it doesn't look like anything other than a mistake. Then open the PDF with Adobe Reader.

  Do not save using the Save on the file menu. It does not work. Save the toolbar that appears above him.

• downloaded Adobe Reader 11.0.16 but can't open the pdf - message "because it comes from a developer that is unidentified.

  Have imac with Yosemite 10.10.4 and recently updated Adobe Reader for the 11.0.16. I need to open an application with A.R. form to enter information, but after changing my default to Preview for this file, I get the message "pdf can not be opened because it comes from an unidentified developer". I don't know anything about changing security settings, which is also mentioned, and do not know if the offender is A.R. or pdf file. Is the file to open from the UK Lotttery Heritage Fund, an organization of very broad reputation, who advised me to use A.R. When I told them that when I had used an excerpt info boxes would not extend as it should, when the text is entered, nor. I don't think it will be a rare problem and would be very grateful for advice because it is rather urgent.

  Thank you, Arnold

• Pro XI Adobe Adobe pro DC and cannot open a PDF file without joining DC

  I signed up for Adobe Pro XI with monthly payments and there are now some how went to Adobe pro DC and ask for me to sign for it and I cannot open any pdf document without joining DC. I don't want to join another that I already paid for Pro XI?

  Hey sarahc84140040,

  If you use an Acrobat XI subscription, then you are eligible to use an upgrade to Acrobat DC without paying any extra.

  You can install and activate your subscription DC Acrobat using the same Adobe ID credentials and access to your PDF documents.

  Please try to connect and let me know how it goes.

• I want TO open the PDF file in Adobe DO NOT FF but updates force me to FF

  My FF decided on 01/12/2012 to open in the browser, the substitution of my settings. No matter what I do, how to change the settings, PDF files open in FF. I totally uninstalled Acrobat 11 and reinstalled Acrobat 10. Always opens in the browser (Yes that means it is FF the problem?)

  My settings in FF were to open in Reader, overridden. Changed to save the file. Overloaded. NO.
  matter what I do, a PDF file open in FF. My settings in FF for years have been to open it in Adobe, but now I can't find the setting!

  So now, haha, PDF open in FF and FLASH is mucked up. So I increased the problems and
  He spent an hour and a half. Can you help me? Who am I (or they) doing wrong?

  Excellent! Who did it! I never thought that, but that's exactly what was wrong. I did use about: config much, so it never entered my mind! Bravo!

  I really appreciate your help. Thanks again!
