ConfirmFolderMove

ConfirmFolderMove came about because trackpads tend to pick up unwanted movement, including accidentally picking up a folder of 20,000 messages and shifting it somewhere it shouldn't be. It takes a long time to fix that kind of accident. confirmfmv pops up a dialog window before doing any moving, stopping the move if cancelled.

You can turn off the preference (folders.drag.confirm) within the extensions window in case you plan to move a lot of folders.
