I cannot open PDF files within Firefox.

I'm running Firefox 3.6.23 on a Macbook pro with version 10.6.8 installed. However I'm unable to open pdf files online. It works on google chrome from the same computer, just not firefox. There is a blank area where the pdf file should open, and nothing happens. I cannot download the file using firefox either. I've tried restarting and such, can you please help me?

Now, I cannot open PDF files that are contained within a website, i.e. a lunch menu that is on a restaurant website.
Does this help with Firefox?

Cannot open pdf files in Firefox.

I cannot open pdf files in Firefox. (I can in Chrome).
I tried Menu - Preferences - PDF - Use Adobe Acrobat Professional. Also tried the same with PDF Browser Plugin 2.4.4
Clicking on a PDF link just opens a blank page.

When I enter about:preferences#applications <Enter> in the address bar, then for PDF it shows:
pdf File (application/x-download) ... Use Adobe Acrobat Professional
pdf File (application/x-pdf) .... Use Adobe Acrobat Professional
Portable Document Format (PDF) ... Save File'''
I would like all PDF's to open in Adobe Acrobat 8 Professional.
Right now none of the PDF's open at all, so opening in Firefox or any other viewer would be preferred over not showing up at all.

Cannot open pdf files with Firefox's built-in pdf viewer

This just started (I think) with Firefox 37.01. This is on Win7-X64. I cannot open pdf files with the Firefox built-in pdf viewer. If I click on the file or try to open it from within Firefox, it brings up a "opening filename.pdf" message. If I select the "Open with" radio button as 'Firefox (default),' it just keeps looping on this process; it never opens. In Tools => Options => Applications, Portable Document Format (PDF) is indicated as 'Preview in Firefox.' I've never had any other PDF viewer installed on this computer. I've tried disabling all plug-ins and extensions, but it still doesn't work. I searched for solutions but haven't found any for this specific issue.
Thanks for the help.

Hello,
Have you tried, to start Firefox in safemode you can do so by following these steps
'''If Firefox is open,''' you can restart in Firefox Safe Mode from the Help menu:
* Click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
'''If Firefox is not running,''' you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac: Hold the '''option''' key while starting Firefox.
* On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
When the Firefox Safe Mode window appears, select "Start in Safe Mode".
;[[Image:SafeMode-Fx35]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, theme, or hardware acceleration. Please follow the steps in the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
When you figure out what's causing your issues, please let us know. It might help others with the same problem.

I have an iMac and cannot open PDF files while working in my university site in Firefox now. How do I fix this please?

Cannot open pdf file with Firefox 11.0

Firefox automatically upgrades the version I am using. Since it was recently upgraded I cannot open pdf files. Am faced with a blank page. I went through some of the suggestions on these pages and when I opened the Tools window, there is a warning:
Firefox PDF Plugin for Mac OS X is incompatible with Firefox 11!
Is there a way around it? Or is it time to say goodbye to Firefox and move to Safari?

When Firefox updates, it turns
off add-ons that are not
compatible with the new
version. In addition, add-ons
that may have been
automatically installed by other
programs without your
knowledge (third party add-
ons) have been disabled. For
more info about re-enabling
add-ons, see the link below.

I cannot open pdf files with Firefox using a Mac 10.5.8 OSX

The new version of Firefox does not support opening pdf files using a Mac 1.5.8 OSX with an Intel processor. Anything I can do?

ios 6 requires itunes 10.6.3 or higher which requires Mac OS 10.6.8 or higher

I use a Mac and cannot open pdf files in Firefox.

Cannot open pdf, either from websites or attachments to emails. Each time that I try I get this menu of "what to open with" and none of them work.. No problems with Safari.

Found a solution on the Apple community forum. Make sure Adobe isn't enabled as the pdf reader, then go into Macintosh hd/library/internet plugins and delete all pdf plugins. Solved the problem!

Adobe acrobat X cannot open PDF files in Firefox, though IE can. What gives?

when I download a page that's a PDF file from the Web, Firefox cannot open it, although Internet Explorer can. I just uninstalled Adobe Acrobat Reader 5.0 because I had Adobe Reader X installed.

When I enter about:preferences#applications <Enter> in the address bar, then for PDF it shows:
pdf File (application/x-download) ... Use Adobe Acrobat Professional
pdf File (application/x-pdf) .... Use Adobe Acrobat Professional
Portable Document Format (PDF) ... Save File'''

Cannot open PDF files in my Hotmail account since this week. Hotmail says it is due to Firefox.

Cannot open PDF files in Hotmail while using Firefox. Using Google Chrome there is no problem. I already have Adobe Reader installed on my PC.

Hi Zwann,
Have you looked at the [[Opening PDF files within Firefox]] Knowledge Base article? There is a lot of useful information in there. They actually list 2 different PDF plugins. I'd give both a try if you are having issues.
Hopefully this helps!

I cannot open PDF files since installing Firefox 4. Have tried everything. Help.

I installed Firefox 4, and now I cannot open PDF files. I have tried everything, including disabling PDF download, re-installing Adobe Reader, etc etc. Nothing seems to work.

I was under the impression Foxit was a pdf viewer rather than an addon for Firefox, but maybe there is more than one application with a similar name.
I did not notice mention of foxit in the help, but add-ons are not always mentioned.

Cannot open PDF files online with Firefox 4, help suggests foxit but don't know what that is?

Earlier versions of Firefox allowed me to open PDF files online, without downloading. Firefox 4 does not allow me to open and read PDF files online, but requires downloading to computer.
Help suggest altering settings in FOXIT READER, manually, but I don't know how to access Foxit reader, if I have it.
Can I alter settings in Firefox 4, or do I have to go back to earlier version.
Thanks

Why can't I open PDF files in Firefox?

I cannot get PDF files to open for viewing in Firefox. I am on Mac OS platform. This seems to be such an ongoing issue. I have followed the troubleshooting procedures to no avail. I like the look of Firefox better than Chrome, but I am switching over to Chrome because PDF's are so much easier to handle on Chrome, and I am sick of wasting time with this. Any last minute tips or advice?

The Adobe Reader plugin may not be working properly on Mac.
* https://support.mozilla.org/kb/pdf-files-are-blank-and-cant-be-downloaded-mac
* https://support.mozilla.org/kb/Opening+PDF+files+within+Firefox
Disable the Adobe Reader plugin in Firefox (Tools > Add-ons > Plugins) and use the external Adobe Reader application or Preview application instead.
PDF files may be found under entries like Portable document or Adobe PDF document or Adobe Acrobat Document.
*Firefox > Preferences > Applications > Adobe PDF document : Use Adobe Reader

Can't open pdf files with firefox

After searching for a certain topic on Google I've tried to open the link with a pdf file, but nothing happens.
I receive an error message as if the Proxy that we use here at the company was refusing the connection, but in fact, I've already configured it correctly. This error started after the last update to Firefox 33.0.2.
I've already tried to change the configurations at Options > Applications > Portable Document Format with the option use Adobe Reader (default) and use Adobe Acrobat (in Firefox), and also installed an Plugin "PDF Viewer", but nothing solved the problem.
Does anyone has the same problem?
Thanks

■ Use '''Tools -> Options -> Applications ->''' <br> then look under content for Adobe Acrobat forms etc;
<br> note a choice of options is usually available
* see [[Options window - Applications panel]]
Firefox is of course a web browser. <br>Acrobat reader is Adobe's program used to read and display the pfd files on your computer. Other programs may be used instead of Acrobat reader. You would normally have the Acrobat program and the pdf file present on the local computer, often both on the same hard drive, if you were opening individual pdf files directly with Acrobat.
Firefox uses a plugin so that it may use Acrobat to open pdf files and display the results within a firefox window or tab. If you do not have that plugin installed, or it is not enabled firefox may be unsure what to do with the file and offer to save it to whatever your default local download location is, without attempting to open the file in firefox.

Cannot open pdf files using optonline email

PDF attachments to optonline emails do not open. It was possible at one time to open PDF files by right double clicking the file bar and selecting "reload page" but that no longer works.

Hi FRANKIMOSSI,
Have you checked to see if your PDF add-on is up to date? I'd take a look at [[Opening PDF files within Firefox]]. There is a lot of information in there and it lists a couple of different PDF add-ons. I'd try both to see if it is localized to just one.
Hopefully this helps!
