2.Launch to http://www.mozilla.org/quality/browser/front-end/testcases/oji/test6.html
3.While applets are running, can't use Ctrl+t to launch any URL, can't use other shortcuts, and can't input anything into text fields.
4.Move cursor to above URL "search mozilla: ", can't input any characters to text box.
