$.ajax broken on cross-site XMLHttpRequests in Firefox 3

Description

Trying to use jQuery's ajax method on a cross-site XMLHttpRequest fails because script is not allowed to call setHeader on these requests. The attached testcase tries to load http://tinderbox.mozilla.org/showbuilds.cgi?tree=Firefox&json=1 using $.get, and fails.

Throwing this in a try{} block should do the trick.

Fixed in [3978]. This doesn't appear to have been just an FF3 problem and in fact didn't work in any browser. The fix was to add dataType == "json" as an allowable remote type. Check the changeset for details.

One problem with the above test case is it used $.get instead of $.getJSON. The new test case sets the dataType correctly.

Version: 1.1.41.2

Actually, this ticket was in relation in something else. In Firefox 3 you can now do X-Domain XHR. Fixed, for real in SVN rev [4149].
