Can someone make a small change to the javascript diffing function? Specifically: Changing this line in PageHistory.php/beginHistoryList() from $url = wfLocalUrl( $wgTitle->getPrefixedText(), "dummy=1"); to $url = wfFullUrl( $wgTitle->getPrefixedText(), "dummy=1"); should do the trick. As is the javascript diff function no longer works in Firefox 0.8. It errors out with: Security Error: Content at http://en.wikipedia.org/w/wiki.phtml?title=Space_Shuttle_program&curid=… may not load or link to chrome://browser/w/wiki.phtml?title=Space_Shuttle_program&dummy=1&diff=0&oldid=2304466. So I suspect the full url will fix the problem and still be compatible with other browsers. -- Audin Malmin - audin(a)okb-1.org Faith is the great cop-out, the great excuse to evade the need to think and evaluate evidence.
