Adding images.

I don't use Firebug. Could you compare the built-in Network Monitor? I am attaching a screenshot for comparison.

Does this still happen with the current release?

Please check the attached image of chrome dev tool we are seeing the on load time 1.16 sec mark in red same I want to know for firefox Network what is the value for on load time , could you please send me the screen shot.

I think you can generate that display yourself. ??

Just now I took the display from that , Please see the attachment , please can you clarify my doubt here we are not getting duplicate calls, but if we check the red line vertically so can we consider that one for on load time, if we go with that it means our on load time is less than 2.56 sec but whenever I am checking on load time in firebug always getting 4 sec. so what you say about firebug its not good to check the performance.

Sorry, I haven't used Firebug for years. They do have some discussion sites where you can inquire. http://getfirebug.com/community
