After sending a e-mail to more than 2 recipients, Yahoo offers a button to create a list to group recipients together. A modal dialog will open and from this point all actions are unresponsive/will hang and user is unable to restore the page without closing. Reproduction: 1) Sign in to Yahoo mail using Firefox 9. (seems to work in 8 and 10) 2) Compose a message to 4 recipients; Fill in subject and body; other fields can be blank 3) Send the message 4) On the following page, there should be a button "Create List" ~NOTE: There may be two buttons labelled Create List -- this is a bug too and does not exist in other branches 5) A modal dialog should open up 5a) Clicking the "Cancel" button or the x on the top right corner should not do anything 5b) Setting a name for the list and then hitting save should lead to a loading screen that will hang

David If it hangs with no CPU usage, please get a stacktrace and attach the file to this bug report https://developer.mozilla.org/en-US/docs/How_to_get_a_stacktrace_with_WinDbg If it hangs with CPU usage, please get a short profiler run and post the URL of the upload here in the bug. https://developer.mozilla.org/en-US/docs/Mozilla/Performance/Reporting_a_Performance_Problem
