A new firefox extension is available for firefox 28 and up! Please uninstall the old extension, then install the new one (available on the Home page). You are not supposed to run the old and new one side-by-side. Configuration is a little bit all over the place, logging in has to be done on-screen (you'll get a screen asking you for credentials) while further configuration must be done in the extension's detail view. Not extensively tested, but atleast catching intel: there is now a version for mobile firefox.
UpoOpu provides intel storage for the webgame Utopia.
It is constantly improving and as such might contain a few bugs.
If you want a new feature or found a bug, you are encouraged to report an issue.
You are encouraged to patch things up!
