Dojo uses style.display='none' to hide inactive tabs, when tab re-activated in FireFox the FlashPlayer reloads the SWF file (in contrast, IE the ContentPane is simply displayed with no loss of context/input etc. in a Flex component). Reproducible: Always Steps to Reproduce: 1.Load FlashPlayer (preferably a simple Flex app) in a Dojo TabContainer 2.switch between tabs 3.Observe Flash/Flex component reload when tab is selected in FireFox Actual Results: I have a simple Flex app that shows a progress bar when loaded, available on request. Also have a simple Dojo application that loads this. In IE, state is maintained when tab deselected/selected. Expected Results: Firefox should maintain state of hidden TabContainer/ContentPane - handling of visibility and style.display should not cause reload of plug-in
This is a known problem, see bug 90268.
