Facebook, navigating with Google Chrome 15.0.874.121 and using Ubuntu 11.10, when i try to comment, chat or give a "like it" the next blank page appears and don't let me do anything:

http://www.facebook.com/ajax/ufi/modify.php

I've tried with, based on what i found in internet:

1. Erasing cookies and cache
2. desynchronize chrome before erasing it
3. Uninstalling chrome with: sudo apt-get purge google-chrome-stable
4. Erasing manually: /.config/google-chrome directory

And nothings solves the problem, Any ideas, would appreciate your help

Thanks
