I also tried "file://///" as generated by Macromedia but it fails too. Firefox simply does nothing. It can be a DOC, PDF, or a folder. It's also impossible to "open link in new tab". Jules is a network server that is accessible locally. All works well with Internet Explorer. The page is served by the HTTP server of Tomcat 5. Thanks Reproducible: Always Steps to Reproduce: 1. click on the link 2. 3. Actual Results: nothing Expected Results: open the related document, for example a PDF file, or open Word with the DOC file. I am developing the corporate intranet site. And we have some pages with lots of simple links on documents (DOC, PDF, XLS, etc). It works with IE but not with Firefox.

see the release notes how to disable this security feature http://www.mozilla.org/releases/mozilla1.7rc1/known-issues.html#psm IMO a duplicate of bug 84128.
