Not able to run test on firefox 6

Hi all,

I am using selenium IDE (HTML) to create my automated test cases.

In order to execute them I am using the selenium-server-standalone-2.8.0.jar

For Internet Explorer 8, i execute this command line and works correctly.

For firefox, I execute the this command line, but the in the cmd window selenium freezes in the following line:
"Checking Resources aliases" (see the attached screen shot)



As a result only one test case is executed and the firefox browser remains open.

I am using firefox 6.

Do you have any ideas about what could be causing this problem and the possible solutions?

If i execute this using selenium IDE, it works correctly.

Please I need your help to resolve this.
Thanks in advance.
Regards,

Why you don't use ff7?
