Firefox links don't open

When I click on a link in an e-mail using Firefox as my default browser, they will not open in Firefox. This applies to PDF and SWF links i.e. PDF LINK: CLICK HERE (Link: http://www.caseyresearch.com/cgcPdfs/crBg20090610034937.pdf)
Similarly on my banking site I can only get partial access to the web sites. When I change to Internet Explorer they all work just fine and I have no problems.
Can anyone help explain what I need to do to solve this problem.

The PDF link opens in FF 3.5, and I have had no problem with three banking sites.
There is an outside chance that certain sites are hard coded for IE.
Two possible solutions: 1. copy the address from IE, and paste it into Firefox.
2. Best with hard coded cases is to use the IE Tab add-on.

 

Ramesh Srinavasan's "Default Browser" (http://windowsxp.mvps.org/defaultbrowser.htm) did the trick for me with one click.

FF is set for my default browser, and links don't work.
I tried the "Default Browser" software and it made no difference.
