I cannot open pdf files in Firefox from links
I cannot use Firefox to open any link the leads to a pdf file, like most user manuals. This is a recent problem. Internet Explorer and Edge do not have this problem. Here is an example link: https://freestyleserver.com/Payloads/IFU/2017_sep/ART38553-001_rev-C-Web.pdf
I tried the option to use Adobe Reader DC but it didn't help.

Hi, if using Adobe DC did not work to open the file which I can please try this : Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove your Firefox program files and then reinstall Firefox. This process does not remove your Firefox profile data (such as bookmarks and passwords), since that information is stored in a different location.
To do a clean reinstall of Firefox, please follow these steps: Note: You might want to print these steps or view them in another browser.
- Download the latest Desktop version of Firefox from this page) and save the setup file to your computer.
- After the download finishes, close all Firefox windows (or open the Firefox menu
and click the close button 
).
- Delete the Firefox installation folder, which is located in one of these locations, by default:
- Windows:
- C:\Program Files\Mozilla Firefox
- C:\Program Files (x86)\Mozilla Firefox
- Mac: Delete Firefox from the Applications folder.
- Linux: If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see Install Firefox on Linux. If you downloaded and installed the binary package from the Firefox download page, simply remove the folder firefox in your home directory.
- Windows:
- Now, go ahead and reinstall Firefox:
- Double-click the downloaded installation file and go through the steps of the installation wizard.
- Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
More information about reinstalling Firefox can be found here.
WARNING: Do not use a third party uninstaller as part of this process. Doing so could permanently delete your Firefox profile data, including but not limited to, extensions, cache, cookies, bookmarks, personal settings and saved passwords. These cannot be easily recovered unless they have been backed up to an external device! See Back up and restore information in Firefox profiles.
Please report back to say if this helped you!
Thank you.
I followed your steps and it didn't help.
Also, to click the link "This doesn't solve my problem", I had to copy this URL into IE: https://support.mozilla.org/questions/1218446?utm_campaign=questions-reply&utm_medium=email&utm_source=notification&auth=bWlrZWczOjR3Yy1mNTZiNjY3MDcwOWE0NzI4NTMwNQ%3D%3D#answer-1113404
The message was "Your organizations policies are preventing us from completing this action for you …"
Hi, from the above error message then it seems like you will need to go through your Windows 10 Settings and inspect what is causing that issue. As well in Settings --> Apps --> Deafult Apps see if you can make Firefox the default for PDF files to open or Adobe DC.
Isn't the builtin PDF Viewer working?
You can check this pref on the about:config page.
- pdfjs.disabled = false
