I cannot open a pdf on mac - am running 17.0.1 on mac os 10.6.8


Hi, I cannot open a pdf on mac - am running 17.0.1 on mac os 10.6.8.

I followed the instructions here: http://support.mozilla.org/en-US/kb/pdf-files-are-blank-and-cant-be-downloaded-mac?esab=a&s=pdf+mac&r=0&as=s but the problem is not fixed - I just get left with a blank screen in a new tab when trying to open pdfs (the downloads folder is also empty).

For example here: http://unetealfuturodeltrabajo.files.wordpress.com/2012/12/esthetic-world-dic-2012.pdf

More Information

PDF files are blank and can't be downloaded on Mac
When you install or update Adobe Reader, it installs a plugin for viewing PDF files inside Firefox and sets that as the default. The problem is that this plugin does not work. In order to view PDF files again follow these steps:
Note: We have blocked the Adobe Reader plugin so this should not be an issue any longer.
On the menu bar, click on the Firefox menu and select Preferences....
Select the Applications panel.
Type pdf into the search bar.
For each content type listed, click on the drop-down menu in the Action column and change the selection to use Adobe Reader, Preview or PDF Browser Plugin (if you are using the Schubert PDF plugin).

You may need to both change your Application preferences AND disable the Adobe Acrobat plugin. To disable the plugin:

Tools > Add-ons > Plugins category

Any luck?
