Crash opening web pages with firefox

Hi,

When I open embedded web pages with Firefox as the browser type I get the following .net error. If I open with Internet Explorer the page is OK, if I open with Chrome I just get a blank white page.

Any suggestions as to what is the issue?

### .NET ERROR ###

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
