Hello,

Since Google Chrome version 21 you can install extensions and userscripts only from the google store (to reduce security risks).
Currently nearly all Ogame extensions and userscripts aren't hostet in the google webstore, so you have to use the workaround to install / update them.

- Store the extension or userscript on your computer (right click on it and choose "Save link ..." )
- Open the windows explorer (or finder for mac user) where the file is located.
- Click in Chrome onto the screw-wrench on the top right, choose "Tools" and then "Extensions".
- Enable the developer mode.
- Drag and drop the stored file into the chrome extensions tab.


See support.google.com/chrome_webs…rx_warning&answer=2664769 -> Steps on adding extensions from other websites
