Can't open pdf files with firefox

Question

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.
