Dozens of Firefox windows open quickly on my IMac when I access a PDF file. Must always ForceQuit.

When I open a PDF file on my IMac, dozens of Firefox windows open very quickly in succession. The only way to stop it is Force Quit Firefox. I use Firefox as my default browser because of this problem. Apple support team had me uninstall and reinstall Firefox and Adobe, nothing helps. Thanks for your help.

This has happened

A few times a week

== Not certain.

Make sure that Firefox is not selected to manage PDF files: Firefox > Preferences > Applications

  • Failed to open one of my Firefox windows open!

    I have about 15 Firefox windows open right now. One of them was probably nearly 50 lozenges goes on it. This single Firefox window open is no longer for me.

    I tried to turn off my different ways of the computer without closing Firefox so hoping that when I restart the computer, Firefox will give me the option to restore the windows and tabs. I had just planned to clear a bunch of tabs in the window of Firefox that had too many tabs running.

    Problem is I can't get the restore window appears. All that happens is that all the latest open Firefox Windows starts automatically without giving me the restore window. Is there a way to get around this? Thank you.

    After two abnormal closures, Firefox should present you with the "embarrassing" dialog allowing you to choose what windows/tabs you want to open. You can change your preferences so that Firefox does after any accident.

    (1) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

    (2) in the filter box, type or paste the session and take a break while the list is filtered

    (3) double-click browser.sessionstore.max_resumed_crashes and set the value to 0 (that's a zero).

    To 'crash' Firefox, you can use the Windows Task Manager (Ctrl + Shift + Esc), processes tab, to complete the process for firefox.exe.

    Be aware that session restore manages a limited number of windows and tabs, as you can see in: config. I guess that these values may be increased a little, but is it browser.sessionstore.max_tabs_undo affecting 50 actually work I have no idea.

  • all minized firefox windows open when I open a new window

    I have several firefox windows open and kept to a minimum. When I try to open a new window in firefox, all minimized windows full and are displayed. I am running firefox 8. How can I fix it so that the minimized window is reduced when I open a new window?

    Under Windows XP.

    This problem may be caused by an extension that does not work properly (possibly Ask.com toolbar).

    Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > appearance/themes).

  • How can I get Firefox to open a Visio drawing that is saved as a .vdx file? Firefox is fine with Visio drawings, stored as a .vsd files.

    I need to store Visio files in VDX format for compatibility of Subversion.
    When I ask Firefox to open a VOD on the network, it shows correctly the file is a Visio file and asks if I want to save it. I select Yes, then the file opens in Visio.
    When I ask Firefox to open vdx at the same location on the network, it treats the file as a text file and open it immediately - no option to open with or save.
    I tried to reset Firefox, but it did not help.
    The application in Settings tab does not show the Visio file types in both cases.
    The underlying Windows 7 file association for vsd and VDX is set on Visio.

    I'm stalking MS Office plug-ins to see if there is no information there.

  • When I download a pdf file, I used to be asked if I wanted to open or save.  Now, the file is saved only. How can I go back to be invited?

    When I download a pdf file, I used to be asked if I wanted to open or save.  Now, the file is saved only. It's really annoying, because the file name of the saved file does not identify it somehow, and I find myself with a bunch of unknown files on the desktop.  How can I go back to being able to view the file when it is downloaded (and so to save it on the spot with an understandable file and to an appropriate folder name)?

    I know you hate Adobe, but this parameter does not have to do with Adobe at all, in fact... This is an internal setting of Firefox.

    Anyway, change go to Tools - Options - Applications and enter "pdf" in the filter field. Change the action associated with this type of file to do what you want, in this case always 'ask '.

    Hi stephenm26904611,

    Thank you for your bug report about the extension to create a file PDF Acrobat being disabled in FF v43.

    It is a known issue and we are working on that.

    We intend to provide support in the future updates.

    Meanwhile, as a solution, you can use Adobe Create PDF extension for Chome and Internet Explorer, or use Acrobat to convert web pages to PDF.

    Thank you

    When I have a pdf file open, I used to be able to click on the "Bookmarks" tab on the left side and allow me to click on every page and delete if I had to.  Now when I click on the Bookmarks tab, this section is empty.  How can I show him each page once again?

    Hi chrismarks1,

    I think you can be confused bookmarks with thumbnails. If you click on the miniatures Page icon (the one above the bookmarks icon), you can delete a page by clicking on its thumbnail, clicking the delete page (icon of the Recycle Bin). Just make sure that you see the PDF file in Acrobat (rather than Acrobat Reader), you cannot remove the drive pages.

    Best,

  • When I receive a PDF file in an email, why must I register before I can open it?

  • When you use firefox, a new firefox window opened and blocked to continue using firefox unless I have a fine. I can't delete the page or even let him. Any help?

    The new window is "http://block.policehunt.org/?id=d04201572567089f9b464bbb1b065531". It is said in very rough English that they recorded me have access to child pornography and in order to unlock my browser, I have to pay $300 through some point of payment. When I try to close the window, a pop-up asks you, "do you want to leave this page? IF you click Yes, it flashes and repeats the same pop-up over and over.

    The English used in the message indicates it is clearly a fraud... it seems that maybe a virus, even if I have an internet virus scanner.

    Any suggestions how to "selectively" delete this 'blocking' window without having to reset firefox entirely?

    Go ahead and force close Firefox by using the Task Manager.

    CTRL + Shift + Esc > process tab > select firefox.exe > 'End process' button

    Then open the currently active settings Firefox folder by using the search box of the start menu to open this short address:

    %APPDATA%\Mozilla\Firefox\Profiles
    

    If you see more than one folder, click on in the most recent. If there is only a single folder, click on in this.

    Search for files beginning with sessionstore. Generally, you will find sessionstore.js and sessionstore.bak. If Windows hides file extensions, you can view according to the method described in this article to support: http://support.microsoft.com/kb/865219.

    Rename sessionstore.js to something like sessionstore_bad.js file, so that Firefox does not restore this last series of windows and tabs automatically.

    Leave this window open, and then restart Firefox.

    If you want to reopen some of the pages of the last session, you can use the tips in the following threads for 'mine' the sessionstore_bad.js file to extract the URL:

  • Firefox crashes when I close a PDF file that had opened a website to my request.

    Windows 64-bit Vista OS. Everything works fine until I close a site open PDF file. Then, Firefox hangs and must be closed and the Firefox process must be completed with the Windows Task Manager. Then only Firefox reloads.

    In case you don't know not, yours is not the current version. Try Firefox
    in safe mode. Let us know how you do.

    ======================

    Try Firefox Safe mode to see if the problem goes away. Safe mode is a troubleshooting mode, which disables most of the modules.

    (If you use it, switch to the default theme).

    • Under Windows, you can open Firefox 4.0 + in Safe Mode holding the key SHIFT key when you open the desktop Firefox or shortcut in the start menu.
    • On Mac, you can open Firefox 4.0 + in Safe Mode holding the key option key when starting Firefox.
    • Under Linux, you can open Firefox 4.0 + with leaving Firefox then go to your Terminal and running Safe Mode: firefox-safe-mode (you may need to specify the installation path of Firefox for example/usr/lib/firefox)
    • Or open the Help menu and click on the restart with the disabled... modules menu item while Firefox is running.

    Once you get the pop-up, simply select "" boot mode safe. "

    If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to understand that one. To do this, please follow article Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems .

    To exit safe mode of Firefox, simply close Firefox and wait a few seconds before you open Firefox for normal use again.

    Whenever I try to download a file (PDF, JPG, DOC), which was attached to an email (I use Outlook WebMail) the document will download very well HOWEVER eight (8!) or more to download windows pop up as if I tried to download that file eight times (or more).
