Is the HTML shown via 'View Source' different from the HTML shown in (Firebug) developer tools?

Question

I\'m using Firefox alongside Firebug Developer tools.

Is the HTML shown in View Source (Ctrl + U) different from the HTML I see when inspecting elements

Answer 1

In Firefox, View Source may reload the page, changing what is on it. See this bug and vote for it if it is bothering you:
