Hi,

You can try to Disable other possibly problematic Extensions in Tools (Alt + T) > Add-ons. You can also try to update the script, or look for an alternative. The script pages and reviews may also have useful tips. The script author may also be able to help.

You can check for problems caused by a recent Flash 11.3 update and possibly downgrade to Flash 11.2 or 10.3.

Thanks Cor-El that helped a lot but now I get the hang when I have two tabs open and the second is a different game on Facebook, Google chrome works fine but not Firefox :(
