You can download the following test files from here.
  • test1
    This page demonstrates how Firefox (3.6.x) freezes in the frame page. When you see a PDF in the right frame, please click the button in it.

    Acrobat JavaScript 'this.getURL("http://www.mozilla.org")' within the PDF displays http://www.mozilla.org in the right frame. But only Firefox freezes. This bug can not be seen in other browsers such as IE , Google Chrome nor Opera.

    Notes: This bug can not be confirmed in Firefox 3.5.x. It is confirmed in Firefox 3.6.x. And this test requires you to set Acrobat JavaScript enabled and to see a PDF within the browser.

  • test2
    If the PDF file is not show in the frame page, there is no problem in Firefox as well.

  • test3
    Actually no Acrobat JavaScript is related at all. Even a normal link in a PDF file within the frame leadsFirefox alone to freeze itself.
