Error message.. Typeerror:COLLAPSIBLE SIDEBOXES. centre is undefined. This message started to show after I started using Google Intergrated Mail. I'm not sure if it's a Google issue or a Firefox issue. However, I would like to fix the problem.
When I call up Gmail (Integrated with calendar) this error message appears and I want to remove it.
Hope you can help... Stuey.
