Debugging Flex apps in Firefox 4

When you want to debug Flex app just start debugger in Flash Builder. It will launch browser, e.g. Firefox 4.

The problem is that when you stop at break point for too long, Firefox 4 will terminate Flash plugin. Default limit is 45 seconds.

This is useful behavior for normal web, but it’s not good for debugging.

Solution is quite easy.

Type URL: about:config

Enter filter: dom.ipc.plugins.timeoutSecs

Change value to -1

I found this solution at:

Happy debugging. :-)
