There are couple things you need to make sure are set up correctly:
1) SWBrowserIntegration service has to be running. Unless there was an issue with the installation, or the service startup, it should be running automatically
2) Toolset Integration Tray Application - you can launch it from the start menu
3) Orion account settings - you need to set your Orion account to enable browser integration. You can do this in Account Settings
1) SWBrowserIntegration service is running
2) Toolset Integration Tray app is running
3) Browser Integration is enabled for my account and as far as I can tell for all accounts.
This IS working fine in IE. Just not FF.
I would recommend to contact our support so that they can assist you.
