Info : Using the new OGame API, the script is able to show all the user info available on Galaxy View (this availability is directly correlated with the API info updating).
After changing the character encoding from ISO latino 1 to UTF-8 the script works fine on the built-in extension manager of Chrome (v 19.0.1084.56) on OSX Lion (10.7.3)
It wont install (at least on Chrome) with a different encoding than UTF-8
