This is actually a FF 4 RC question...but I can no longer open PDF files...the page just goes blank. No option in applications to set a PDF viewer as default. Help!

How do you open PDF files in FF4 RC? The application section in options doesn't have PDF as an option to associate with a program. Whenever I click on a PDF file, I just get a blank tab.

Hi there,
You're running an old version of Safari. Before troubleshooting, try updating it to the latest version: 6.0. You can do this by clicking the Apple logo in the top left, then clicking Software update.
You can also update to the latest version of OS X, 10.8 Mountain Lion, from the Mac App Store for $19.99, which will automatically install Safari 6 as well, but this isn't essential, only reccomended.
Thanks, let me know if the update helps,
Nathan
