When I drag drop a message to Firefox it is moved to “Deleted Items”

You are here:
  • Make sure you update Firefox to the latest version
  • Reset Firefox to default settings:
    In the address bar type or paste: about:support
    > Enter/Return
    > Click the button: refresh Firefox
  • Advanced option:
    In the address bar type or paste: about:config
    > Enter/Return
    > Click the button promising to be careful
    > In the search box above the list, type or paste autos and pause while the list is filtered
    > Double-click the browser.tabs.remote.autostart.2 preference to switch the value from false to true
  • A workaround for this issue is pressing ctrl while drag & dropping the message
