From Galaxytool wiki
FoxGame is an extension for the Mozilla Firefox Browser.
It has a feature to send data to a galaxytool installation but if you want to keep the original Toolbar you have to pay some attention at how you configure FoxGame.
Foxgame adds some buttons to upload data to various tools. These buttons may cause errors at the Toolbar because they are added by manipulating the ogame source code. The reduced galaxyview or highlighted debris fields cause no problems. They are recognized by the Toolbar since version 1.4.
Having the Foxgame database options enabled ( adding extra buttons to the galaxyview ) will make the Toolbar stop working.
