Firefox 21 not proceeding to URL

[Jerry]

Using Firefox 21, if I enter this URL:

http://www.nclawreview.org/documents/91/1/wegner.pdf

nothing happens. The PDF is not displayed nor is there any evidence
that Firefox did anything at all.

Now, entering the same URL using the same version of Firefox on a
Windows machine, it works perfectly. No surprise there. Why is it
failing on the FreeBSD machine? I posted on another forum and was told
it works under Linux, so it must be a FreeBSD problem. Can anyone
confirm this or have an idea what the problem is?
