Have anybody encountered this problem? How to solve this? Thanks in advance.

EDIE:selenium 2.5 version has solve this problem.

I had this issue after upgrading to Firefox 8, when running selenium v 2.9.0.

It was fixed by upgrading to the latest version of selenium (2.13).

 sudo pip install selenium --upgrade

(if you're using the Python flavour)
