Iframes stop loading the script on tab change in firefox

[SangishettyPallavi]

Hi,
I have Main application which consists of Two tabs. On clicking on any of the tab respective application will be loaded. i.e. TAB1 loads sampleApplication1 and TAB2 loads sampleApplication2 (sampleApplication1 and 2 are loaded as sub-applications).In TAB2 an IFrame Component is used to load HTML content.
When the application is loaded,if we try to open the TAB2 immediately and then navigate to TAB2 the contents in the iframe are loaded completely in the Chrome where as in Firefox the contents are partially loaded and stops the execution of the script loaded in iframe. Is there any workaround for this issue? Can anyone please help me out in finding the solution for this issue?

Thanks in advance,
Pallavi
