Firefox will not open pdf files & changes the options/applications settings?

At first, with default settings, Firefox would not open pdf files & came up only with a blank screen & no file reference. Going to options/applications & changing the default to a new installation of Adobe Reader still brought up a blank screen but this time with the file ref. Oddly though, attempting to open any pdf file would then change the setting under applications back to Use Adobe Acrobat (in Firefox). But this doesn't work. So what do I need to do to get Firefox to open pdf files correctly using Adobe Reader?

  • What can I do to rectify the situation in which Firefox will not open pdf files in the browser, even though I have already used all the help suggestions to no avail?

    I have tried everything Mozilla has suggested. Still when I click on a pdf, I get the message that the browser cannot open a pdf. I have gone through the help protocol, and it does not work.
    I have uninstalled Firefox and reinstalled it, and still not able to open pdf files within the browser.
    What else do I do, except go to IE or Chrome and just leave Firefox completely???

    A possible cause is the presence of a PDF plugin from an older Adobe Reader plugin in the plugins folder in the Firefox program folder.

  • Firefox will not open PDF files from my financial website, but IE will.

    When I try to open reports in Fidelity, UBS, etc, the file downloads, but removes the extension so it won't open and I get the message "Unknown file type". I tried the same procedure in IE, and the files open without problem. I do not want to use IE. How do I get the files to open. This is a recent (~5 days) problem.
    Thanks,
    Bill

  • Can't get Firefox to NOT open PDF files in the browser

    I would like Firefox to always ask whether I want to open or save a PDF document. Instead, it always displays the file in the browser and pops up a toolbar. In Tools/Options/Applications pdf files are not listed. However "PDF Xchange Viewer Document" (my default PDF viewer) is listed and the action is set to "Always ask"; yet it never asks. Why?

    Such actions are usually linked to a specific MIME type and if Firefox doesn't obey and ask what to do then you may have created this action for the wrong MIME type.

    Make sure you have the latest Adobe Reader installed for your OS.

    Did you try using Preview. If you control click on the PDF on your desktop you can use the "open with" option.

  • Safari will not open pdf files.

    Safari will not open pdf files, instead I get a blank grey screen. How can I get a viewable and downloadable screen/file? Tried Alt/Option to view and it doesn't work either. Firefox and Chrome will not work either.

    For Mac check the Safari preferences.
    General to set the options for opening links from applications.
    Tabs to set the other options.
    Hold down the command key to open any link in a new tab.
    Sorry, gave up windows several years ago.

  • I need to make a pdf document, made in photoshop, 'page turn' and then add it to my website. I know I can do this in indesign but indesign will not open pdf files for some inexplicable reason. Any ideas how I can do it without completely starting again?

    I need to make a pdf document, already made in photoshop, 'page turn' and then add it to my website as an e-brochure. I know I can do this in indesign but indesign will not open pdf files for some inexplicable reason. Any ideas how I can do it without completely starting again?

    Hello waitingone,
    please try this (all terms are translated from my German programs to my best knowledge):
    1. Did the creator of the pdf file enable the import options?
    2. See import options: choose an other visibility option for your layer.
    3. Let you show the import options and click into one with a black background and try these out (often a gray is selected).
    4. See trimming: try the different modes there. Often works: "Media".
    5. Is the pdf file (eg from Word) correctly created?
    6. Is the PDF file protected? >>> no import possible.
    7. If that does not help, store the pdf file in Acrobat, repair possible errors, run the PDF Optimizer before placing in InDesign.
    Good luck!

    Make sure you have updated Acrobat X to the latest version 10.1.3.  They updated the PDF plug-in in 10.1.1:  http://kb2.adobe.com/cps/837/cpsid_83708/attachments/Acrobat_Reader_ReleaseNote_ 10.1.1.pdf#page=4

  • Help - "Acrobat is being used by another application and cannot open PDF files until the other application is closed."

    Hello,
    I searched this site and google for this error terminology and come up dry.  I support a user who has been for years using Acrobat 5 (yes, I know...) to read files in a client DB program, as well as other PDF files on their PC.  In the last week or so, they have started gatting this error "Acrobat is being used by another application and cannot open PDF files until the other application is closed." any time they attempt to open a PDF file attached to an email (via Outlook).
    It is my understanding that they cannot upgrade to a newer version of Acrobat because of limitations of their client software, but had not previously had any issues viewing PDF notes from the DB, and PDF attachments in their email.
    I have tried uninstalling and re-installing, as well as tried using Adobe Reader 7 & 9 in conjunction with Acrobat to try to get around this issue, but have not been successful.
    Any ideas?
    Thanks,
    Jesse

    I don't have an answer to your technical problem. The product I assume is Acrobat that you are talking about (based on the post title), Adobe is the company name. This is a good place to ask questions on Acrobat if folks can figure out what you are talking about. They will ask for the product version number (like AA9.3.3), operating system, and other applications if appropriate. Also, just what you are doing that generates the message.
    As for Adobe, you are not likely to get an answer from them here in the user forum. You will be lucky if you can get an answer if you can contact them and not be on hold for more than an hour (sorry, this is why a lot of folks end up in the forum).
    So, to help others try to answer your question, what are the products and versions involved? What OS? What are you doing when the message comes up.

  • Firefox will not open .aspx files. I can open them with IE. What's up?

    I updated Java, uninstalled and then re-installed Firefox. It will not open .aspx files. Internet explorer opens them just fine. .pdf files open fine also. Don't know?

    How would I change the aspx to pdf? As far as going to the menu/applications, I don't see an aspx in the list? Sorry, but I'm pretty rank in this department. Maybe it is the website and not Firefox, although as stated, IE opens them fine.

  • Firefox will not open now - I just updated my privacy settings, and cleared cookies - what happened?

    I changed the privacy settings on Firefox preferences, including clearing cookies, history and cache, and now Firefox will not open at all. It said it had to restart after one of the privacy changes, but it didn't and now won't open by the dock icon or thru applications. What happened, and how can I correct the issue to start using Firefox again? Thanks.
