Firefox doesn't display PDFs in browser all of a sudden

I noticed earlier that all of a sudden I can't view PDFs files in Firefox. I tried plugins, updating Firefox and everything on my Mac, and any other options I could find but nothing seems to work. I installed the recommended plugin for viewing pdfs, but it just views a blank white page (instead of "missing plugin" that, when clicked, didn't give me any information).

Remove all other plugins you have installed for viewing PDFs and install [https://www.adobe.com/products/reader.html Adobe reader]

Firefox doesn`t display any pictures. All sites work with mistakes, but work at IE or Chrome is correct.

Problems with e-mail - cann't read the whole text of the letter, cann't answer.

If images are missing then check that you aren't blocking images from some domains.
*Check the permissions for the domain in the current tab in "Tools > Page Info > Permissions"
*Check that images are enabled: Tools > Options > Content: [X] Load images automatically
*Check the exceptions in "Tools > Options > Content: Load Images > Exceptions"
*Check the "Tools > Page Info > Media" tab for blocked images (scroll through all the images with the cursor Down key).
If an image in the list is grayed and there is a check-mark in the box "<i>Block Images from...</i>" then remove that mark to unblock the images from that domain.
Make sure that you do not block third-party images, the permissions.default.images pref should be 1.

There are also extensions (Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images.

"Display PDF in Browser" setting - $500 reward for the solution

The corporate policy requires the "Display PDF in Browser" setting to be unchecked for all applications, this is to open the PDF document in new reader instance but our specific application needs the reader to be opened in the same browser even if the preference "Display PDF in Browser" is unchecked.... The setPreference from javascript (html) doesn't seemed to work... How do i make this work? I am looking for programatic way to set this preference in HTML javasript or Java Applet or ActiveX or any other means. I am currently using JS and Object tag, the only functions that we need at this point are page navigation and getting current page using JS.
Also, I need the links the browser to open in new browser once the PDF is loaded... do I need to reset the preference once it is loaded for the links to open in new browser? How can this be progrmatically achieved without altering the original PDFs?
I realize that this may be difficult and am looking for workarounds or alternate solutions to meet my req. $500 for anyone who could can provide solution.. Please email me [email protected]
thanks,
- Ray

Convince your IT people to allow folks to set their preference to display in browser.

Adobe Reader X - Disable "Display PDF in Browser" via Registry

I'm trying to configure my organization's Windows workstations so that web-based PDF files open in Adobe Reader rather than in internet browsers. I have been able to configure Adobe Reader 9 installations to open web-based PDF files in Reader rather than internet browsers by using the following registry setting:
Hive
HKEY_CURRENT_USER
Key path
Software\Adobe\Acrobat Reader\9.0\Originals
Value name
bBrowserIntegration
Value type
REG_DWORD
Value data
0x0 (0)
My problem lies with Adobe Reader X: I used the following settings in attempting to prevent Adobe Reader X installations from opening web-based PDFs in internet browsers:
Hive
HKEY_CURRENT_USER
Key path
Software\Adobe\Acrobat Reader\10.0\Originals
Value name
bBrowserIntegration
Value type
REG_DWORD
Value data
0x0 (0)
Hive
HKEY_CURRENT_USER
Key path
Software\Adobe\Acrobat Reader\10.0\Originals
Value name
bAllowByteRangeRequests
Value type
REG_DWORD
Value data
0x0 (0)
Hive
HKEY_CURRENT_USER
Key path
Software\Adobe\Acrobat Reader\10.0\AVGeneral
Value name
bBrowserDisplayInReadMode
Value type
REG_DWORD
Value data
0x0 (0)
I've only had partial success, though. Internet Explorer respects the registry settings and opens web-based PDFs in Reader X. Firefox 14.0.1, though, ignores the registry settings and opens web-based PDFs in Firefox.
Is there a different registry setting I should be using so that Firefox sees "Display PDF in Browser" unchecked and allows web-based PDFs to be opened in Reader X? Is there another method I should be following for deploying this setting to Adobe Reader X clients?

Hi,
We'll, you've educated yourself well. Unfortunately, Acrobat products can't control what browsers do so uniform behavior is not possible. The setting is Adobe's best attempt and forcing some consistency.
The ReadMode setting only controls what happens in the UI after the PDF is open.

What is your operating system? Browser? Reader version?

Display PDF in Browser Option

I am able to open a PDF file from a particular protected Website. I can fill in the required info, but when I attempt to Save/File it back to the site, the following pops up: "For security reasons your return could not be saved. Please ensure that the 'Display PDF in Browser' option is selected under the Edit-Preferences-Internet Settings in Adobe Reader."
Adobe Reader XI, Internet Explorer 10 & Windows 7 are loaded on my PC.
I cannot trace 'Display PDF in Browser' under settings, but using Tools>Manage Add-ons>Toolbars and Extensions>Show>All Add-ons, I can see that 'Open PDFs in the Browser' is Enabled.
I also used the Registry Editor: Adobe>Reader>exe to confirm the Name, Type & Data in the string value: (ab), REG_SZ, C:\Program Files\(x86)\Adobe\Reader11.0\Reader\AcroRd32.exe
No help is forthcoming from the Website, despite me logging a call to their service centre
Does the problem lie at my end, or the Website?

Hi Ben,
I manually added the registry setting but it made no difference.
I uninstalled 10.1.4 and reinstalled 10.1.3 and with 10.1.3 I am able to view a PDF in IE when launched from the command line.
I re-downloaded and reinstalled 10.1.4 and retried and now I can view a PDF in IE when launched from the command line.
Strange.

Display PDF in browser issue in 9.1.1

We deployed the 9.1.1 msp update to all of our clients but we realized that it unchecks "Display PDF in browser," so now I need to figure out how to get that checkbox rechecked for every current user and any new user that logs on.
I know that all I need to do is delete bBrowserIntegration in HKCU\Software\Adobe\Acrobat Reader\9.0\Originals but this will only change for the currently logged on user. For shared machines that we currently have deployed in our environment how to I change this setting for all of the users that are currently not logged on or for any future users that may log on?
Thanks for any help.

I would create a script to go into the active setup folder that will run when each user logs in. Appdeploy is a good website for stuff like this. Here is a link that will might be able to help you create a active setup script if you're not sure.

'Display PDF in browser' whats the default?

Can anyone tell me definitively what the current default setting has been for whether Preferences/Internet Options/'Display PDF in browser' is checked or unchecked?
I'm curious to know as well if it has changed with 8, 9, and 10?

For all three the default is "checked".

Open PDF Slow Problem and Edit Registry to Disable "Display PDF in Browser"

There is around 400 users who were installed Acrobat Reader 9. But it is found that they open our intranet pdf very slow due to NETBIOS problem. The alternative solution is to disable the browser integration feature.
But how can I set Group Policy or Windows Registry to disable the "Display PDF in browser" feature for all the users?

If your users use Internet explorer, you can disable the add-on. to disable the add-on you will need to know the version of IE they are using. the most commonly used scripts to do that are kixstart or .VBS scripts.
e-mail me if you need any help with the script

Todays update to 7.1.0 broke "Display PDF in browser"

I do ***NOT*** want PDFs displayed in my browser.
I ***DO*** want PDFs displayed in a separate Acrobat window.
Version 7.0.9 was working this way until the update to 7.1.0 went in today.
Now, regardless of the of the setting of the Edit --> Preferences --> Internet --> Web Browser Options --> "Display PDF in browser" checkbox, all PDFs ARE being displayed in the browser window.
How do I disable this behavior or uninstall this last update?

I have managed to fix my problem with PDFs only opening in the browser. I went to MSIE(v7) Menu --> Tools --> Manage Add-Ons --> Enable or Disable Add-Ons... --> Add-ons that have been used by Internet Explorer --> [find/highlight the line with file = AcroIEHelper.dll] --> Disable --> OK --> Restart the browser (and maybe the PC).
As for 7.1.0 not being a real update, that is wrong. It is real.
Read about it here:
http://www.adobe.com/support/security/bulletins/apsb08-13.html
It says:
"Adobe recommends users of Acrobat 8 and Adobe Reader install the 8.1.2 update and users of Acrobat 7 install the 7.1.0 update to protect themselves from potential vulnerabilities. This is an update to resolve the issues previously reported in Security Advisory APSA08-01."

Safari won't display pdf in browser and I do not have adobe reader or ply ins

I've been checking the posts and all the discussions/questions and answers but the only thing I have been able to find about problems displaying pdfs in browser have to do with adobe plug-ins. I never had adobe reader and checked in /library/internet plug ins and never found those plug ins. I then downloaded and installed adobe reader X and got rid of the plug ins in the library and that still has not solved the problem. Whenever I click on a link for a pdf it just automatically downloads the pdf. I just want to view the pdfs in the browser.
Thanks for the help

Hi,
You probably won't have to reinstall Safari. Two things you can try. If you open Adobe Reader and go into the 'Internet' section of its preferences, you should be able to disable the browser plug-in. Some times that alone isn't enough, in which case, browse to HD/Library/Internet Plug-ins/ and move the Adobe plugin out of the folder. Restart Safari for the changes to take effect.

Reader X " display PDF in browser" is checked but greyed out

Hello
I have a user who wanted to print double sided by default when opening a PDF on a web page. I found that by downloading the PDF, not printing from a browser, the user can print double- sided. But when I go in preferences the option to uncheck " display PDF in Browser" is greyed out? I'm tried running reader as admin, logging out and logging in as admin, restarting the PC, running all updates. I was going to edit the registry next but wanted to see if anyone had been having this problem? THee is no Acrobat on this Dell laptop, only Reader X. It is a Windows 7 PC, fairly new. Any help would be appreciated.

Please update to the latest version of Adobe Reader i.e. 10.1.2 and enable the double sided printing as in the below figure:
Hope this helps.

Adobe Reader 9.1 Disable Display PDF in browser

Is there a registry setting I tweek to uncheck the box for Display PDF In Browser? The only ones I could find grayed out the box but it didn't un check the box.

I'm just confirming what anhnguyen7902 posted.
This was tested against Acrobat Reader 9.3.1. I exported all of the registry keys from HKEY_CURRENT_USER\Software\Adobe\ with the "Display PDF in browser" setting enabled and disabled. Below are the only relevant differences when changing this setting from within Acrobat Reader.
With the setting enabled, keys under [HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\9.0\Originals] are...
[HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\9.0\Originals]
"bHostBasedCM"=dword:00000001
"iPSLevel"=dword:00000000
"sProofingSpace"=hex:55,2e,53,2e,20,57,65,62,20,43,6f,61,74,65,64,20,28,53,57,4f,50,29,20, 76,32,00
"bDisplayedSplash"=dword:00000001
With this setting DISABLED, keys under [HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\9.0\Originals] are...
[HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\9.0\Originals]
"bHostBasedCM"=dword:00000001
"iPSLevel"=dword:00000000
"sProofingSpace"=hex:55,2e,53,2e,20,57,65,62,20,43,6f,61,74,65,64,20,28,53,57,4f,50,29,20, 76,32,00
"bDisplayedSplash"=dword:00000001
"bBrowserIntegration"=dword:00000000
The difference being the bBrowserIntegration key being present and set to dword:00000000 when this option is DISABLED, but the key being completely removed when the setting is ENABLED.
While writing this post, I decided to test it against Acrobat Reader v4.2.1. The results were the same.
Hope this helps.

What is the default for the "Display PDF in Browser" setting?

What is the default for the "Display PDF in Browser" setting in Adobe Reader 9 and X?
Also, are any statistics available on what proportion of users have this setting set to on?

For all three the default is "checked".
