Introduces a preference that allows users to be prompted before moving folders to prevent accidental moves that may take a significant amount of time to wait out and undo.
Updated to work with Thunderbird 68. Unfortunately, the options window does not function, so you'll have to modify preferences by hand if you need to change them through the config editor (but you likely wouldn't have changed these settings from the defaults and probably won't need to change them down the road either - disable the add-on entirely if you need a quick way to shut its functions off).
