I am debugging a Web page that performs several AJAX requests.
To this effect I sometimes find it convenient to reissue an AJAX request (from the Network pane of Development Tools, right click + "Resend") and would find it even more convenient to open the request in a separated tab, as was possible until, if I recall correctly, four or five months ago.
Now the latter option does not work, likely because of some security tightening - the "new request" might be seen as a different context, I don't know. The AJAX endpoint receives no cookies, so it can't load the appropriate state, and restarts as a blank slate with a new cookie, which makes the reply useless to me. Even worse, at this point the new cookie value is propagated to the originating window, effectively crashing the entire debugging session.
Is there some way of disabling this option and reverting it to the older, less secure behaviour, on my own development Firefox only?
