Consider https://bug98654.bugzilla.mozilla.org/attachment.cgi?id=77369 with the popup blocker disabled. Chrome, Opera and IE open a new window/tab and load the Mozilla front page into it. Firefox used to but doesn't anymore. As far as I can tell, Firefox behaves according to the spec: Setting window.location aborts the parser synchronously and the first subsequent document.write() then implies a call to document.open(), which aborts the navigation started by window.location. Is there a mechanism in the spec that makes this work as in Chrome, Opera and IE and I'm failing to read the spec right? If not, what's the mechanism that causes Chrome and IE to load the Mozilla front page into the newly-opened window/tab in this case? Note that in this modified case http://hsivonen.iki.fi/test/moz/write-after-location.html (requires a click so that there's no need to adjust the popup blocker) the console says "before" and "after" but not "later" in Chrome and IE. Opera says "before" and "after" and then the opener script ends with a security error, because write is already a different-origin call, i.e. setting window.location has immediately made the document in the new window different-origin. -- Henri Sivonen hsivonen at iki.fi http://hsivonen.iki.fi/
