Comment 41 for bug 728798

Just tested the (German) 3.6.15 build1 candidate from ftp://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/3.6.15-candidates/build1/unsigned/win32/de/ and still have the same issue with it as in 3.6.14

STR:
- open http://www.java.com/de/download/help/testvm.xml
- page loads with an java applet telling if you use current plugin or not
- change to i.e. www.google.com on the same tab
- again open http://www.java.com/de/download/help/testvm.xml (either by entering address or simply going back to last page)
- now the java applet shows only ~40% topmost content, remaining rectangle is filled grey
- reloading with F5 or Ctrl-F5 reloads page but plugin area remains broken
- opening a second firefox doesn't help, here the plugin is broken on the first try
- only closing all firefox instances and starting a new one allows the plugin to work again, but only once

The java test page is the German one, strangely it doesn't happen with the English one: http://www.java.com/en/download/testjava.jsp
