Hi Pete,

We have tested our online tours in firefox version 2.0.0.11, and the tours display at the same size as in IE. We also made new tours and the test result was the same. Maybe you can try this: go to Options->Content->Advanced, please do not select the option of Move or resize exiting windows. If you still has the problem, please contact support@easypano.com with the detailed information about your system, Flash player version and hardware information. Thanks.

best regards
